Thread: iPhone 3G weak network signal issue

  1. #1
    Default iPhone 3G weak network signal issue
    I have a problem with an iPhone 3G with network coverage. it is always weak, but far stronger when 3G is enabled. in the last few days i have tried to work out what the problem is.

    The problem remains on many different OSs and Basebands. i'm currently on 3.0.

    I have another iPhone 3G on 3.1 and it ALWAYS has much stronger signal when i compare.

    I have swapped parts between the two iPhones and today worked out that the issue follows the main logic board (so it isn't the antenna etc).

    does anyone have any ideas. The phones are out of warranty. there is no obvious visible damage on the logic board itself and all the connectors look fine.

    Yes, now, but the phone has run on 2.2.1, 2.2 etc not jailbroken, with the exact same issue.
