With Windows Phone 7 out, everyone has forgotten about the other Microsoft handsets, the allegedly Sidekick-derived Turtle and Pure cellphones. Someone got a peek into the firmware, which confirms some of the rumors about these "not-so-dumb cellphones".
• The user interface is done in Silverlight, which the cellphones will obviously support.
• Turtle—Pride in the CDMA version—will have a 320 x 240 resolution.
• Pure—Lion in the CDMA version—will have a 480 x 320 display.
• Both firmware are tied to Nvidia Tegra.
• They seem to run a Windows CE6 core.
• There are references to Premium Mobile Experiences all through the firmware.
With the strong push on social networks in Windows Phone 7, it feels like these are now outdated and out of place. [WMExperts]
