Headphone jack, power button, volume and mute not working
I dropped by Iphone 3gs and since then, the power button, head phone jack, mute and volume buttons are not working...But everything is working good. I have been to apple store expecting they might repair it, but their answer was no use to me. I decided to try myself..Can anyone please help me know the problem and how to repair it. Tried to open it but did not understand what to do after opening it.
Is this a good question?
