Guys, i hope any of you iphone experts can advice me on this case, and here's the scenario. My uncle actually owns this iphone in which i think it's 2nd generation (i'm asking on behalf of him). It was fine for about half a year but just about a month ago it started to act awkwardly when he migrated from Malaysia to Australia. He said the iphone just freezes every 2-3 days after rebooting. And when it freezes, he can't switch it off whatsoever he have to wait until the battery runs flat, recharges the phone and reboot. So i was wondering if there's anything to do with software being outdated or stuffs like that.

Can anyone advice please? Thank you very much in advance.

Whoa, doesn't sound too good. But well okey, he said that the last thing he remembered before it started to act like that was when he transfered the photos from his iphone to his laptop. He said he hadn't installed anything thus far

Great advice guys, and thank you very much. Although i'm not familiar with Apple, but i'll sum this up for my uncle:

1. Download FW2.1 and installer 4
2. Connect iPhone to PC
3. Format the iPhone

is that correct?
