Iphone 3g freezes when not plugged in!

I've had my second hand iPhone 3g for about 8-9 months now. It's been absolutely fine and i've not experienced any issues...unitl now....


I upgraded to 4.2.1 last week and since then i've gradually been experiencing problems. I'm not saying it's related but it seems that way. The most recent is by far the most annoying, almost making the phone unusable....


The phone works fine when plugged into a computer or power source. Literally no issues. Once unplugged the phone pretty much freezes/locks up straight away. After a bit of investigation i found that if the phone is powered on while plugged in I can unplug it but as long as the screen doesnt lock it works. So essentially when unplugged and i lock the screen the whole thing freezes. It also won't start up unless plugged in.


Any ideas? I've done the following:


Restore from backup

Restore in recovery mode and resync backup

Restore in recovery mode and don't resync backup

Restore in DFU mode and resync backup

Restore in DFU mode and don't resync backup


NOTHING HAD WORKED!

Any ideas guys?
