T-Mobile G2

The successor to the T-Mobile G1. Released in late 2010, it is the first phone on T-Mobile's lineup that has HSPA+ capabilities. Before, T-Mobile's HSPA+ network was restricted to wireless broadband cards/modems.

Known in other parts of the world as the HTC Desire Z, the G2/Desire Z are both HTC Vision phones, and as such can run ROMs of each other with virtually little to no lag at all. The Desire Z is unique as its namesake comes from the slider hinge that reveals the physical keyboard. Instead of sliding straight up, instead, it slides up and over, thus giving it a sort of Z-shape motion.

When it comes down to rooting the device, the process has been somewhat simplified from what it was two years ago, but the problem is that "one-click" rooting methods like SuperOneClick and Z4root don't work. Instead, you first need to gain temporary root access, and then use the Android Terminal Emulator to gain S-OFF and something else, at which point you can gain root access.
