First Microsoft Windows Phone 7 Series devices to boast 480 x 800 pixel displays, HD2 owners sigh
Even though Microsoft's big MIX event is still days away, the Windows Phone 7 Series development platform is already pretty well defined. It's also clear that Microsoft wants to keep things tidy for developers by requiring all WP7 phones to meet a certain base-level spec. Now, thanks to a post from Microsoft's Shawn Hargreaves, we know the display resolution for the first batch of Microsoft's next generation phones: 480 x 800 (WVGA) pixels at launch, with a future update that will introduce a 320 x 480 (HVGA) native resolution. Dedicated hardware will ensure image scaling across all those pixels without taxing the GPU. That allows game developers, for example, to write to a lower resolution (requiring less horsepower) and then scale up as required while remaining compatible to a variety of screen resolutions. Now, for those playing along at home, the HD2 getting ready to launch on T-Mobile in the USA is also WVGA and it features a 1GHz Snapdragon processor from Qualcomm, Microsoft's WP7 silicon partner. So we can assume (but not guarantee) that it meets the image scaling hardware requirements described by Hargreaves. Man, if only the HD2 had three-buttons. [Thanks, Cytrix]
LG's first Windows Phone 7 handset shipping as early as September
Our buds over at Engadget Chinese are just reporting back from a sitdown it had with LG Mobile in Hong Kong at a Chinese New Year event. The most tantalizing bit of truth is confirmation of that September launch date rumor for its first Windows Phone 7 Series device. However, this time LG padded the date a bit and said it would launch sometime between September and November. Of course, the only official word so far, has Windows Phone 7 launching before the "holidays," so we'll take what we can get. Maybe Mr. Ballmer meant Halloween?
Windows Phone 7 development policies and guidelines leaked?
We expect to learn a lot more about Microsoft's plan to entice developers to Windows Phone 7 at the MIX 2010 developers conference. Until then (March 15-17), aspiring WP7 devs have to rely upon rumor and innuendo to feed their curiosity. So here you go: three purportedly official Microsoft docs from January that provide a glimpse into Microsoft's Windows Phone OS 7.0 Application Platform. First up, the docs claim that WPOS 7.0 is built around Silverlight, XNA (like the Zune HD), and the .NET Compact Framework -- a mostly clean break from WinMo's past as far as developers are concerned. Native apps are restricted to OEMs and mobile operators in order to extend the experience and functionality specific to a phone or network. Even then, they'll be limited to a set of managed APIs that Microsoft will audit during the app submission and provisioning process. Sound familiar? As you'd expect, the OS supports preemptive multitasking -- not that Microsoft will necessarily allow its devs (OEMs, mobile operators, and independent software vendors) to send their apps to the background. The primary development tools include Microsoft's Visual Studio 2010 and Express Blend used in combination with a Windows Phone emulator.
