So it did work.
I had to install CWM 2.5.0.3 in order to flash it since it uses the old script system, but now that the newest Radio is flashed I get a lot better signal strenght from my room, always 4 bars/H! Used to be 2 bars/E!
Havn't tried GPS yet, but it didnt work from indoors, it could say i was in my city but not what street. Roughly 2km accuracy.
Now I need an app that is free AND can mount /system/bin as rwxrwxrwx... Root explorer is expensive, and I'm a student...
es file explorer can mount system partition as writable
