If there are any questions that the T-Mobile G2, made by HTC, is a stock Android device devoid of any HTC customizations, those concerns can now be laid to rest. A leaked “Test rom for HTC Vision / T-Mobile G2 (Android-Froyo 2.2)” reveals that the HTC T-Mobile G2 will indeed be a stock Android device, where the benefit of not having any customizations is that updates can get pushed to the device a lot quicker.

An important discovery of the leaked ROM is that it seems that the G2 will use a Qualcomm MSM7X30 chipset, which brings some advanced features for multimedia lovers who use Android, including, according to Android Police:

-720P video encoding (recording) and decoding at 30FPS

-Integrated 2D/3D GPU’s with OpenGL ES 2.0 and Open VG 1.1 API support

-5.1 surround sound output

-Up to 12 megapixel camera support

-Integrated GPS

-Support for processor speeds between 800MHz and 1GHz (Scorpion CPU’s, same as Snapdragon’s)

This leaked ROM confirms the WalMart listing depicting that the G2 is a “with Google” phone, meaning that the device won’t have any UI overlays.

Update: As one of our readers noted, a “with Google” designation may not necessarily mean a stock Android device; our reader’s European edition of Samsung’s Galaxy S smartphone has that designation and also TouchWiz, making it a customized Android smartphone.

The T-Mobile G2 also goes by the codename of HTC Vision and will be among the carrier’s first smartphones with HSPA+ support for faster download speeds.
