Hi all. For some reason the bottom row of icons on my home screen (row above the silver dock) no longer responds to my key presses, swipes etc. It was working fine last night and assuming I didn't abuse it in my sleep, I have no idea what's gone wrong. I've tried a reset, restore, dfu restore and nothing seems to fix it. Although it sounds like a hardware problem to me, the on screen keyboard and calculator both work fine. Unfortunately I can't get to an Apple store to see a 'genius' until Friday so if anyone has any ideas, let me know! Neil.
