Is it possible to fry the power/logic board on an Iphone. My phone has been dead for a few weeks now. No response at all. Have been down all the roads of restore etc. Would a battery replacement help? Phone replacement is not possible as I'm in Australia. Please help as I've no hair left to rip out due to frustration!!http://images.macrumors.com/vb/images/smilies/mad.gif
