I have a 3GS that is not under warranty I use it as a iPod touch just the other night all of a sudden the power button on top and the vib switch don't work at all the phone was not dropped or anything and it has been in a otterbox case for months. I have managed to get the top power button to work sometimes if I hold the top of the phone on the front and press while u press the button .. the vib switch I can not get to work although It does work when I turn it on in settings .. So any idea what the issue is it has not gotten wet either .. I have replaced digitizers and LCD screens in the past so I do know how to do the work just curious how hard it is to find out the issue and fix it ?
Thanks
