iPhone 3gs restore trouble
I'm a complete newbie to this forum so please bear with me.
My phone started heating up recently whilst using google maps and I got a message saying I need to restore the phone before I can make phone calls again. I tried and it failed to restore giving me an unknown error 23. Then I tried again by putting the phone into DFU mode and it looked promising - apple logo with progress bar appearing to be 100% completed - then I got a new error code 1002.
So digging around forums hasn't got me any further so I wandered if anybody could advise. Details are:
Previous iPhone Os version: Sorry, can't remember - this would be original version that shipped when I got it 2 years ago.
Windows XP SP3

Many thanks in advance.
