2g problem,turns itself of.
1st time poster here,thanks for any help.
My daughter and I both have 2g's which I purchased around June 2009,I got hers of Ebay. Over the past two weeks her phone has been turning itself off maybe 3-4 times a day.It is unlocked and jailbroken and had os3.0 installed and the battery has been fine.I sent it of for repair and had it updated to 3.2,new battery and unlocked/jailbroken. I received it back on Tuesday and all has been OK untill 20 minutes ago when my daughter said it had turned itself of twice today ! When I mentioned this to the repairer he said that the only other thing that could be the problem is a replacement mother board but this would cost around £200 ! Can anyone offer any assistance please ?
