hey
I have recently bought a iphone 2g second hand, when i first got the phone it was already jailbroken soo i decided to restore the phone and start from stratch. it was runnign 3.1.3 i believe then and after restore it wouldnt recognise my sim... but i downgraded to 3.0 and now my sim is easily read.

The only problem is 3.0 is a veryy bad firmwire i find my battery dies farr too quick and i want to update but anytime i try to update it to 3.1.2 or 3.1.3 it doesnt read my sim.

any idea's on how i can safely update?

Thankss
