iPhone warm and frozen

[SkydiveGuy]

I have had no problems with my iPhone 3G until I upgraded to the 3.1 firmware.

Lately I have been noticing it gets very warm and it is frozen. To get it up and running again, I need to hold down the 2 buttons until it "reboots".

Is this a problem with the firmware or something unrelated (such as a problem with the phone itself)?

How do I downgrade to the 3.0 version of the firmware to be on the safe side?

Thanks.

Did this make anyone else smile. Especially as it makes perfect sense.

Personally I would backup my pictures and do a clean install (no restore from backup). You will lose all settings and sms history but if you can live with this it should rule out software.
