Which OS should I run on my 9900?
Just wondering which would be the best OS to run on my 9900. I'm currently running .585 which I must admit, the battery life is not as good as when I was running the previous offical OS released by my carrier. Now I'd like to install either the official .590 or the leaked 7.1.0.190. Out of experience which would you say is better/smoother?
Need Best 7.1 for 9900 on T-mobile in USA
Can anyone confirm if this version of 7.1.. is the best is to use on a new 9900 with T-Mobile? My only real reason for upgrading the os is to get the Wifi calling to work. I'm lost without my UMA from my old 9780.
