Hi guys thanks for looking.

I keep loosing AT&T signals on my 1.1.2 iPhone.

I used 4.6bl unlocking solution. I have att sim. It used to work perfect before with Turbo Sim but now since I used that even with turbo sim it keeps loosing network. It stays active until I am using the phone but if I press sleep button then after couple of minutes I loose the network. And as soon as I go in the phone application it starts back.

Any 1 have any idea ???
