Tomorrow is the day when Windows Mobile 6.5 is expected to hit the ground running officially. It is expected that upgradeable devices will receive free upgrades from the older version 6.1 of the OS.
At this time, I am not sure whether or not the Sony Ericsson Xperia X1 will receive an official upgrade. However, I have had the proviledge of running WinMo 6.5 on my X1 via custom ROMs made available by various developers. Besides finger-friendly icons, it does not offer much more than what currently obtains on WinMo 6.1.
Other new features that 6.5 offers include My Phone (data synchronisation) and the Windows Marketplace (an application that lets you purchase compatible apps for your device).
Do you own a Windows Mobile smartphone? Is it eligible for an upgrade? Do you have any expectations for Windows Mobile 6.5?
