Good news for everyone who's been waiting for Windows Mobile 6.5. According to a Twitter update by the Windows Mobile Developers Team late last week, work on the stopgap mobile operating system from Microsoft is finally complete. This doesn't necessarily mean your phone is due for an update right away, but rather that it has been sent to manufacturing, and now we have to wait for manufacturers and carriers to roll out upgrades for the current 6.1 release.

Windows Mobile 6.5 is a relatively minor update focused on changes to the user interface and its touch-friendliness. Phones carrying the operating system are expected to hit the market sometime this fall. But Microsoft is already working on a newer release of Windows Mobile, namely version 7, with devices based on it expected in the first half of 2010. In any case, if you are in the market for a new smartphone, you might also want to consider waiting a few months before taking the plunge. There are several exciting alternatives coming out shortly - like the much awaited Palm Pre, the HTC Pro 2 and probably an update to the iPhone in June.
