I have been out of the ROM game for a while. I stayed on Liberty v2.0.1, Android version 2.2.1 for the logest time and really enjoyed this ROM but now I would like to go to the latest one to see if I have been missing anything with all these developments. How do I go to the latest ROM? Is it as simple as download the zip file and go into recovery and install the zip even with this old of a liberty rom? Also the only reason I stayed with the rom I am on was because I had the wireless tether app. Am i still able to use a wireless tether app with this latest rom build?
