I know this has been asked before, but most replies are very old, from like a year back. Which OS is the best to keep constant T-Mobile EDGE? I have 5.0.0.384, I believe I can simply use swap-a-radio to keep the OS and just change the radio file. Can anyone help? I have it sometimes but almost never when I use an app, is this my fault? I'm using epc.tmobile.com as the TCP/IP AP. Should I use a different one? Thanks for your help.
