    Default Dropped iPhone - Lost GSM Signal ---> Solution

    Just thought I'd post in case others have a similar problem to me.

    I dropped my iPhone, and besides a few scratches, I lost GSM reception. I'd usually get 1 bar (in an area which I knew had a good signal strength). All the other features of the iPhone worked, including entering my sim pin.

    So I decided to open it up and see if anything might be wrong.

    After much effort and a few scratches I got it open and to my surprise found that the antenna cable that connects the communications board to the GSM antenna wasn't sitting correctly.

    I lifted the cable of its connector (on the comms board) and reseated it. My GSM signal strength went to 100%, and the phone was now usable.

    So it would seem that I dropped it in such a way that the cable's connector popped off partially.

    I was surprised at this because most people report that these cables have been glued down. This was not that case in my iPhone for both the GSM and WiFi antenna cables.

    So if something similar happens to you, it could be worth trying..

    OK, it might be the same situation with mine.

    I dropped my iPhone a few days before noticing the heavy signal losses, I must say tho' that it didn't fall very hard. it fell from aprox. 1m on a carpet @ work. i thought it should not influence anything...

    anyway, now after reading your post i am thinking of this possibility too.
    so, please tell me how did you open up your iPhone, because i can't see any place/spot where i could start off.

    thanx again for sharing the info.

    Hi,

    I have the same problem:

    - lost signal in a runtime delay of +- 1 - 2 min.
    - make calls is impossible
    - if lost connection - playback over the speakers is breaking up (playback imposs.)
    - if lost connection - playback over headphones - OK.
    - vodaphone card in Germany

    I dropped my iPhone around the same time as you did and got "no service". Tried unbrick; went back and forth betweem different firmwares. Nothing worked. Started using the iPhone as an iPod.

    Today after reading your post, I opened it again and examined the connector on the comm board. It was half out. Pressed it in and now have full signal!!!

    Thanks a lot.

    Ok, for all users that dropped iPhones, you have two options if you live in the U.S.A or have an apple retail store close. You can ask for an appointment at the Genius Bar in any Apple Retail Store, then go to the Apple Store, and tell the problem to the Genius, tell them you dropped the iPhone. If it doesn't work, they will offer you a replacement for a new phone. Same as you have, for only $199 plus tax. Or either you can visit www.iresq.com which is an apple authorized technic center and check for a repair, you will have to send the phone to them, but it's safe and apple recommends it.
