Hi there
I have a OOB 1.1.1 which is unlocked and working fine when not in sleepmode.

When my phone enters sleepmode the signal to my sim-carrier dissapeares and ppl. cant call me - they go direct to my voicemail! The phone is on but no calls?
When i press the homebutton and the screen lights up, I can see that the signal is gone soon thereafter the signal returns and im again able to make and recieve calls!

My battery cant live with a phone that needs to be lit up all the time

Please help - i feel ive tried everything!
