You've got questions, we've got answers (no disrespect to RadioShack intended). Besides releasing rate plan details, AT&T has also posted answers to some of the lingering queries that new and existing AT&T customers might have about snagging themselves an iPhone 3G. Here are a few that we hope will answer questions that readers have frequently been asking us.

So the iPhone costs $199 or $299, right?Sure, Steve Jobs has touted the $199 price tag for the iPhone 3G, but as with anything where a non-Apple company is involved, the truth is not quite that straightforward. If you're a new customer to AT&T, you will pay $199 for the 8GB model or $299 for the 16GB model, as long as you also sign up for a 2 year contract.

If, however, you are an existing AT&T customer, it will depend on your upgrade eligibility. If you are eligible for an upgrade and your account is in good standing (check your My Account page AT&T's Web site to find out if you qualify), you can also take advantage of the $199/$299 pricing. Otherwise, you can purchase an "early upgrade" which will run you $399 for the 8GB or $499 for the 16GB model. Both of those cases will require you to extend your current contract for another two years, and you'll have to pay an $18 upgrade fee to boot.

Can I get an iPhone without signing up for a two-year contract?No. Well, not yet anyway. According to AT&T, a "no-commitment" version of the iPhone 3G (perfect for those of us with commitmentphobia) is "coming soon", and will run $599 for the 8GB model and $699 for the 16GB model. Yowch.

What about prepaid plans? Can I sign up for one with the iPhone 3G?'Fraid not. According to AT&T's cutely named iReady checklist (PDF link), prepaid plans are not available for iPhone 3G.

I want to buy iPhones for me, my dog Ralphie, and my Aunt Marge; can I do that?Nyet. AT&T says you may purchase only one iPhone per person in line. Your Aunt Marge and Ralphie will have to wait in line for their own.

If I buy a new iPhone 3G, how do I transfer data from my old iPhone?Fortunately, iTunes will take care of that. Make sure you sync your existing iPhone with iTunes before trying to sync your new phone so that all your data is current.

Will my new iPhone 3G be able to retrieve my existing voicemails?Apparently not. AT&T says, "Check and clear your voicemail. Any existing voicemail messages will be lost once your new phone is activated." So if you were hoping to retain that hilarious message your friend sent you from their bachelor party, you might want to find some other way of recording it.

What do I do with my old iPhone once I've got my shiny new iPhone 3G?Well, whatever you want, really. You can hand your old phone off to your friend or family member who can then activate it themselves via iTunes. AT&T provides full details for how to do so in this PDF. If you decide not to pass your old phone on, here are some suggestions for what to do with your old unit.

Alternatively, there are software programs out there that will probably let you turn it into a pretty functional iPod Touch.

Not all of this week's news involved global financial turmoil: while IT budgets are being cut and AMD is breaking itself up, a security tool was released for Firefox that prevents "clickjacking" and Microsoft said that Windows 7 will fix issues in Vista's user account control feature.

1. Economic malaise hits IT industry : Disappointing earnings from some IT companies, fewer initial public offerings, lowered earnings forecasts -- all are part of the grim global economic outlook. On the bright side, though, IBM reported this week that its net income rose 20 percent in its third quarter and maintained its profits will be strong for the full fiscal year.

2. AMD to spin off chip fabs to raise funds : Advanced Micro Devices is splitting into two companies, with one designing chips and the other making them. The company also said that two investment funds owned by the Abu Dhabi government will provide capital to AMD and help it compete better with Intel. The news was hailed by analysts, investors, customers and employees as a way to strengthen AMD, particularly in the harsh economic climate.

3. Firefox extension blocks dangerous Web attack : An update of a free security tool for Firefox blocks "clickjacking," one of the most dangerous and vexing problems on the Internet. Clickjacking happens when a Web user clicks on an invisible, malicious link without knowing it. The tool, called NoScript, now includes ClearClick, which can tell if a Web page contains a hidden, embedded element. Users of NoScript who click on such links will be asked if they really want to do that.

4. Microsoft to improve Vista's problematic UAC in Windows 7 : Microsoft is tweaking the user account control feature in its Windows client OS and admits that what was meant to be a security feature in Vista has been a hassle for users. The idea behind UAC in Vista is to give primary PC users more control of applications and settings, but it hasn't quite worked out that way. "What we've learned is that we only got part of the way there in Vista and some folks think we accomplished the opposite," said a blog post attributed to Ben Fathi, Microsoft corporate vice president of development in the Windows Core Operating System Division.

5. Microsoft elaborates on Oslo : Microsoft shed some more light on its Oslo vision for model-based software development this week, detailing the "M" declarative modeling language and the Domain Specific Languages concept that are integral to the overall Oslo package. The company also offered reassurances to developers thattheir role is not being minimized by this raising of the level of abstraction.

6. Apple to hold special notebook event on Oct. 14 : Apple sent out an invitation to reporters to attend an event next Tuesday, saying that "the spotlight turns to notebooks." We assume this means that new Macbooks will be out in time for the all-important holiday shopping season.

7. For a promising IT career, go east, young techie : The IT job market had tightened up even before global financial turmoil gave us all a whack, but opportunities are more plentiful in China, India and Russia, according to analysis of growth trends. Working in such countries also can be good for the old resume. "IT is going global. The IT profession is going global. Developing product for markets all over the world is something you have to learn how to do. Overseas work is a huge enhancer for IT professionals," said Rob McGovern, CEO of JobFox, an international IT employment agency.

8. Mono 2.0 lets .Net apps run on Linux: Considered a major upgrade, the open-source Mono 2.0 runtime leverages Microsoft's .Net Framework 2.0 programming model, letting developers build desktop and server applications using Microsoft-based environments and deploy them across multiple platforms, including Windows, Linux, and Mac OSX. By bringing apps beyond Windows, Mono will help developers reach a larger audience.

9. 11 Microsoft security updates due next week : There will be no rest for weary systems administrators next week -- Microsoft expects to roll out 11 security updates, with four of them rated critical. The monthly patchathon will apply to bugs in Windows Active Directory, Internet Explorer, Excel and the Microsoft Host Integration Server. Besides the critical patches, six others will be rated important and one will be moderate.

10. NASA: Messenger sends back never-before-seen Mercury images : NASA's Messenger spacecraft transmitted images of Mercury to scientist this week, proving them with data about parts of that planet that have never been seen before. The Mariner 10 mission in the 1970s identified the Kuiper crater on Mercury, the planet nearest the sun, and an image of the crater was among the first to be relayed to NASA. Messenger took hundreds of photos of Mercury as it got within 125 miles (201 kilometers) of the planet's surface.

A new Forrester Research study that polled more than 200 SAP customers found widespread discontent over the vendor's recent decision to shift customers to a pricier Enterprise Support offering, and also provides tips on how customers can mitigate the increased cost.

SAP announced in July that Enterprise Support would replace its basic and premium support options. Enterprise Support costs 22 percent of a customer's license fees, compared to 17 percent for basic support. The additional costs will be phased in over the next few years, and new charges won't begin until Jan. 1.

But Forrester clients voiced a number of common gripes.

Eighty-five percent of the clients interviewed described minimal utilization of the Basic Support offering. "The average customer claims to connect with SAP fewer than six times a year -- the equivalent of buying a comprehensive but expensive insurance policy and rarely utilizing it," the report states.

Customers also complained to Forrester about the time it takes SAP to meet requests for new features.

"Customers believe that the maintenance dollars paid to SAP should go to filling in key functionality gaps in the software. However, there are a plethora of examples where key functionality requested two to four years ago by multiple customers in the same or different industries were not delivered in SAP R/3 4.7, let alone available in SAP ERP 6.0," the report states.

Clients "want to know how much of their support dollars really go back into reinvestment versus profit margins," it adds.

SAP has cited a number of reasons for its decision, such as greater complexity in customer environments, and argues that Enterprise Support provides a higher level of benefits for customers -- points the Forrester report does not dispute.

To mitigate the increased cost of maintenance, customers should seek steeper discounts on licensing deals, according to Forrester.

Another tactic would be to create a long-term "SAP containment strategy," which could include taking a look at other vendors. "Many SAP clients with whom we spoke have begun the process of evaluating Oracle Siebel, Salesforce.com and others for customer relationship management as well as Siperian, Initiate Systems and IBM for master data management."

Customers also should consider third-party options for support. While one company, Rimini Street, has announced plans to provide such support, it has not yet begun doing so, and even when it does will focus on only SAP's R/3 products.

The Forrester report's results stand in contrast to SAP's past contention that while customers may not like to pay more money, they understand the value of the new service.

An SAP spokesman was given a copy of the report on Friday, but did not immediately provide comment on its findings.

The collective sigh of relief when Apple lifted the iPhone NDA, which had prevented developers from discussing iPhone programming, came not just from developers, but also from educators, authors, and publishers. With the NDA gone, iPhone-related books can be published, and conferences can be much more detailed, leading to better education.

Publishers and authors who had books written were forced to shelve them because publishing the material would have broken the guidelines of the NDA. However, with the NDA removed, users can expect to see an abundance of information hitting the market, targeting everyone from developers to end-users.

[ Special report: IT's guide to the iPhone ]

"It was huge having the NDA lifted," said Bill Dudney, trainer and co-author of the upcoming book "iPhone SDK Development" (Pragmatic Bookshelf, 2008).

Like many other authors, Dudney had a book written about the iPhone, but couldn't publish the book without breaking the NDA. Now, Dudney -- along with countless others -- can bring his product to market. (A quick search for  iPhone books on Amazon.com shows a number of titles available for pre-order.)

An abundance of books on the market isn't the only benefit we can expect to see. Conferences will now feature better sessions because speakers and trainers will be able to speak freely about what it takes to make a good iPhone application.

iPhoneDevCamp organizer and co-chair of O'Reilly's iPhoneLive conference, Raven Zachary said he is excited about what this means for future conferences. Zachary said they have tentatively added an introduction to iPhone development session at the upcoming conference, which is something they couldn't have done before Apple lifted the NDA.

In previous conferences, speakers would have to talk about Mac development tools and try to relate them to the iPhone, without speaking about the iPhone -- a tough task.

The NDA stifled growth in the development community simply because new developers had a limited amount of resources to seek help. Now, Dudney said, trainers can speak freely and actually help attendees with questions they have about developing for the iPhone. With new developers come new applications and innovation, which only helps the platform.

Perhaps not coincidentally, a week after lifting the NDA, Apple announced the iPhone Tech Talk World Tour, a series of free tech talks about the iPhone for developers. Topics include an introduction to Objective-C and Cocoa Touch, how to integrate the iPhone into an IT environment, submitting your app to the App Store, and iPhone game development

The end result for iPhone users should be a better choice of applications as developers continue to push the envelope of innovation.

The U120 will feature similar specs to its predecessor, the Wind U100, which is powered by an Intel Atom processor. Customers will be able to choose between a 120GB hard-disk drive or a 40GB solid-state drive. The U120 also includes 802.11n Wi-Fi connectivity and a built-in 3G modem.

It is expected to be priced around £350 ($595) and available by December.

Shedding more light on its Oslo vision for model-based software development, Microsoft this week elaborated on plans to preview Oslo technologies, offering code names and citing the company's DSL (Domain Specific Languages) concept as a lynchpin of the platform.

A Community Technology Preview of Oslo is due at the Microsoft Professional Developers Conference in Los Angeles on October 27. Featured in the CTP will be a declarative modeling language now being identified by the code name "M," as well as software modeling tool code-named "Quadrant.

A repository for integration between models also will be part of the CTP. User feedback on the CTP will help determine the overall road map for Oslo technologies, said Robert Wahbe, Microsoft corporate vice president of the company's Connected Systems Division, during an interview this week.

With Oslo, Microsoft seeks to provide another layer of abstraction for developers and make development easier; models become the applications. Business analysts also could make changes to models. For example, an analyst could change an application that requires two managers' approvals for lunch expenses exceeding $100 to requiring these approvals for a $50 lunch, Wahbe said.?

"It's easier in many cases to look at a model and see what it's trying to do rather than look at hundreds of thousands of lines of code," Wahbe said.

With the M language, ISVs and developers could build textual DSLs, he said. A DSL enables a developer to write down intent in a way that is close to how a developer is thinking about a problem, Wahbe said. M also can be used to build data models.

"The idea of DSLs has been around. What we're trying to do with Oslo is make it easier for mainstream developers to use models in general," Wahbe said. Microsoft, as an ISV itself, will use DSLs for building domains for activities like workflow and databases.

"[The] notion is that M is excellent at building these DSLs in an easy way," Wahbe said. "In turn, once you have that DSL, what it does is it lets you produce something that the platform can execute directly."

A model is translated to XAML, which can be executed by the platform. Oslo also can work with multiple runtimes from platforms like Java if developers customize the Oslo tools.

Quadrant, meanwhile, provides a way to author models visually. "The way to think about it is M lets you build textual DSLs and Quadrant lets you build visual DSLs," Wahbe said.

Oslo will be featured as part of the Visual Studio product family; the company has not yet announced which version would include Oslo. While Oslo at first glance might appear to be minimizing the role of the developer by raising the level of abstraction, Microsoft believes it is just a natural step in the evolution of software development that does not put developers' jobs at risk, Wahbe said.

"Developers can deliver higher-quality applications faster," he said.

With Oslo, Microsoft has "definitely raised the bar," said analyst Nick Gall, vice president of the enterprise architecture team at Gartner.

"The Oslo approach to modeling is a refreshing new approach. That said, it is ambitious," Gall said.

"Any attempt to do really do model-driven architecture is ambitious. We've been trying to do executable models for 25-plus years, and all to date have failed," such as with CASE (Computer Aided Software Engineering) and Object Modeling Group efforts, said Gall.

Microsoft is attacking the two core issues of modeling: translating from models into executable code and the functional aspect of an application, in which functional models must accommodate nonfunctional aspects of an application such as security and systems management, Gall said. Microsoft has not yet completed the integration with nonfunctional models, he said.

Oslo integrates with existing applications, according to Microsoft. It brings together a connected view of models and builds on existing investments on top of the Microsoft platform. Microsoft also is working with ISVs on solutions built using Oslo, including line-of-business applications and DSLs, the company said.
