Soon after the news which confirmed the official upgrade path of Windows Mobile 7 for HTC HD2, folks over at XDA have dug deep and found out some references made to Windows Mobile 7 in the latest HTC Sense 2.5 Build 1922. This version of HTC Sense is from the leaked version of T-Mobile US 2.01 ROM for HTC HD2.

Last month, we informed you about the possibility of HTC HD2 getting Windows Mobile 7 upgrade. But now according to a tweet posted by HTC’s Russian twitter account, it looks like HTC HD2 has been confirmed to get Windows Mobile 7 upgrade when it is released in Q3/Q4 of 2010. Translated version of the tweet is as follows.

It seems like Windows Mobile 6.5.3 is going to drop before the major version 7 release, which is scheduled for late 2010. In Windows Mobile 6.5 API documentation at MSDN (Microsoft Developers Network), WMExperts have found out references been made to Windows Mobile 6.5.3, which indicates a new minor version release over the current version 6.5. The said references can be found in “Developing Widgets” section of Windows Mobile 6.5 documentation.

The HTC roadmap that was leaked some time back revealed that HTC is set to release three Windows Mobile based handsets in the first half of 2010, the HTC Photon, HTC Trophy and HTC Tera. None of these mentioned devices can be graded as high end devices. The roadmap, thus brought somewhat disappointment to HTC fans.

Phil Moore, Head of Microsoft Mobile Division in UK has confirmed that phones with Windows Mobile 7 wont be available until late next year. He announced this in a Q&A session held at the ‘Connect’ technology summit in London. This news means that we are not going to see handsets with Windows Mobile 7 anytime before last quarter of 2010.

Windows Mobile 6.5 (or 6.5.3) Build 28002 is out already and it finally brings a new native on-screen keyboard which is optimized for more finger friendly touch operations. Windows Mobile OEMs like HTC, Samsung and Sony Ericsson have already been shipping their newer handsets with skinned version of the original stylus-friendly keyboard for finger friendly navigation. But now from Windows Mobile 6.5.3 Build 28002 and onwards, Microsoft has finally updated the age old on-screen virtual keyboard that has been a feature of Windows phones since Pocket PC’s era.

A source closed to MSMobiles has confirmed that HTC HD2 will be receiving an official free upgrade to Windows Mobile 7 once it is out in Q4 2010. This makes sense because HD2 is the first phone which meets all the hardware chassis requirements laid out by Microsoft for a phone which will be powered by Windows Mobile 7, including support for multi-touch through its massive 4.3’’ capacitive display.

You can’t get Windows Mobile from a store and install it on any cell phone you want. Same goes for the iPhone OS, Symbian, Palm, Android and others. And as we all know, Apple exists due to its eco system. This is the same eco system that inspired Microsoft to develop Zune with the Zune Marketplace and desktop software. Even the Xbox 360 is like iPods, iPhones and the Zune.
