My iphone seemed to pack it in last night.
The issue is the connector at the base seems to be knackered - it refuses to charge from either PC or wall unit and the PC cannot see it. I've tried with three different leads.
It was absolutely fine, this happened without warning and I can honestly say that since I unplugged it to head to the shops, drove there and back and when I got back to charge it for the night - kaput.
It has had a relatively...enthusiastic life with me, but this is a bit sudden.
