As HTC has recently announced the Android 2.3
Gingerbread update for their HTC Desire HD and HTC Incredible S, so it
makes perfect sense for HTC to release the version of the T-Mobile G2
update as well. So, someone decided to take things into their own hands and leaked the official G2 Gingerbread ROM version.
It is a new 2.13.531.8 version instead of the previously leaked 2.13.531.5.
