Not sure if I am the only one having this problem but I have a 2G on tmobile jailbroken... on the 2.2.1 fw I had awesome reception and signal... since upgrading to 3.0 fw I have had horrible signal-- it will often go from full bars to no bars, or searching, or no service.
Evan when I have full bars the reception when making a call is very scratchy...
Is this a firmware problem or a tmobile problem? Should I call tmobile or just wait for a fix from the dev. team? Are others having this problem too?
I tried to downgrade to 2.2.1 and i keep getting error code 1600, and I have tried about 15 times and got frustrated...
The baseband didn't change on 3.0 with the iPhone 2Gso there should not be any service changes from 2.2.1 to 3.0. In order to downgrade you have to DFU restore to 2.2.1.
