Really? I just was able to install it and I have the Froyo 2.2 update.
He is talking ROM, which means he has a custom ROM. Its why I havent messed with rooting yet because all of the roms are 2.1 kernels with older versions of Android core apps on them half of the time. I would love a complete copy of our current rom but with root unlocked so I can disable sense, install the stock dialer and delete the sprintware.
