iPhone 4, firmware 4.1,BB 5.14.02,prepaid T-Mobile.
When this phone is standing on a table shows signal depending on location,but sometimes 3 bars inside the house.
As soon as i pick it up,no signal or no network!
Any help with this problem ?
Of course is jailbroken and unlocked by the vendor.
Another 3GS works fine,if in the same location.
