Apparently the once HTC Obsession is getting a name change to the HTC Diamond3, and word has it the HTC Diamond3 is destined for both AT&T and T-Mobile sometime later this year reports an article over on wmpoweruser.

Apparently according to a ‘reliable source’, the HTC Obsession will not only get the name change to the Diamond3, but will ship in June 2010 but there may be a delay for some reason. Furthermore the HTC Diamond3 will definitely be a Windows Mobile 7 smartphone rather than a Windows Mobile 6.5 version.

Also, the word is as the previous HTC Diamond experienced ‘poor sales’, the HTC Diamond3 will not be available in CDMA.

Specs for the HTC Diamond3 are GSM/HSDPA, 3.7 inch capacitive AMOLED touch screen with multitouch, a 5 megapixel camera with auto-focus and flash, HD 720p video, 4GB internal storage, microSD expansion up to 32GB, and a 1GHz Snapdragon processor.
