New Windows Phone 7 details; Live ID integration and OEM restrictions

WMPoweruser has posted some juicy information regarding Windows Phone 7's underlying architecture. The leaked architecture guide was found to contain some previously unknown information regarding the upcoming OS. Here's what we didn't know before:

  • Your phone is heavily linked to your Windows Live ID (much like an Android phone is to your Google account)
  • Users will be asked to log in at first boot and asked to accept the EULA
  • Hardware will be verified through a Genuine Windows Phone certification before an ID will be accepted
  • Without a Live ID, contact sync, use of the Marketplace, and use of Microsoft services are not possible
  • Phone processes will be able to utilize up to 1GB of the phone's RAM (high limit takes future hardware into account)
  • No Bluetooth 3 support
  • OEMs are responsible for Direct3D drivers
  • OEMs will be limited to 6 pre-installed apps, taking up a max of 60 MB
  • OEMs cannot install trialware
  • OEMs can change the default search engine in Mobile Internet Explorer, but cannot remove Bing as the phone's default search provider

WMPoweruser also notes something interesting regarding the way these phones will handle file storage. "Windows Phone 7 devices will use Microsoft Unified Storage System for user files, meaning applications will not be able to distinguish between files on internal storage and main memory.  This also means if the user removes the memory card the smartphone will only be able to make emergency phone calls, but nothing else."

Windows Phone 7 devices are expected to ship around holiday season 2010.
