The Windows Phone 7 mobile operating system appears to having one or two problems ...

Phantom Data Usage

Microsoft has told BBC News that it is investigating why some handsets running its Windows Phone 7 software are sending and receiving "phantom data".      Several net forums detail complaints from people that say their phones are automatically eating into their monthly data plans without their knowledge.      Some have complained that their phone sends "between 30 and 50MB of data" every day; an amount that would eat into a 1GB  allowance in 20 days.

Application Limitations

Someone found out the hard way what happens when you install more than 15 applications that use the push notification system in Windows Phone 7. To put it bluntly: it stops working. The first 15 push enabled apps work, but install more than that and the rest simply don't get updates.

But it's not a limitation, it's a feature -- according to Microsoft.


Marketplace DRM Cracked
Bad news if you're selling in the Windows Phone 7 Marketplace. This hack can ...

... successfully pull any application from the Marketplace, remove the security and deploy to an unlocked Windows Phone with literally a push of a button. Alternatively, you could just save the cracked XAP file to your hard drive.

Neither the app nor methodology were released, but it the hacker claims it took only 6 hours to develop. Then he developed a patch:

The crack was not intended to harm the WP7 Marketplace, but was intended as a critique of Microsoft's seemingly lax security. To help protect developers in the interim, while Microsoft develops its own solution, Tobias has posted code that developers can deploy in their apps to help protect them from piracy.

Meanwhile open source Android continues to chalk up more than 300,000 new registrations every day.
