It’s here. Cyanogenmod 9 rom based on Ice Cream Sandwich for the T-Mobile myTouch 4G. XDA senior member febycv has  just released a fresh alpha build of CM9 for the myTouch 4G. The new ROM is compiled from the latest Cyanogenmod source, and should surely give your device a shot in the arm.

The build, like I mentioned before, is an early alpha, meaning some bugs are to be expected. CM9, across the board, is under heavy development and does  have bugs serious enough to let down one’s larger than life enthusiasm of trying it, but it’s just a matter of time before these are ironed out and steady builds are released. So, lets get the goods.

Warning!

The methods and procedures discussed here are considered risky and you should not attempt anything if you don’t know exactly what you are doing. If any damage occurs to you or your device, including a bricked, non-functional device, we won’t be held liable. You have been forewarned!
