I have the TMobile HTC G2. Firmware is Android 2.2, kernel 2.6.32.17-g9ab3677htc-kernel@and18-2#1. What is the codename for this? Is it Froyo? I see lots of posts about Froyo and don't know if they apply to my phone. I've also heard of 'gingerbread' and others so not sure what my build is called. Thanks!
