The Windows Mobile enthusiast site named WMPoweruser has learned that HTC Obsession, which we reported about earlier is set to launch later this year on AT&T and T-Mobile US as HTC Diamond3. Their report confirms that the smartphone is scheduled to ship sometime in June this year, however this date is likely to slip to Q3/Q4 launch in 2010.
According to the latest Windows Mobile 7 findings by WMExperts, HTC Obsession could very well be the first Windows phone which will ship with Windows Mobile 7 come this fall. Microsoft may even show it off at the upcoming Mobile World Congress, where they are highly expected to unveil Windows Mobile 7 for the very first time.
