    I upgraded my phone to 4. but want it JB again. i eventually managed to downgrade to 3.1.2 using redsnow. Everything is working as before except the phone app, giving me 1 bar signal no operator and no network details, i didnt see it activate during restore or redsnow. Anyone know how to reapir this with out going back to 4.
