So I received an SMS message and ignored it, then the phone vibrated again shortly after to remind me I had a message and I went to unlock the phone to read it, the phone just died.

Pressing either button does not wake it up.

Plugging it in to the computer or the mains charger doesn't wake it up either.

What gives? Any way to do a hard reset or anything to force it back to life?

Luckily I still have my older generation jail broken iPhone and am using it until I can revive the 3G model.

This should help. How to enter DFU Restore Mode

Also, since it's definitely still under warranty, why not just take it in to get fixed??

Good luck!

You know you bring up an interesting point: how is a hard reset done in a phone where you cannot remove the battery?? The manual doesn't address how to do that??

Cheers lad, even though it wouldnt turn on the DFU mode thing worked (after the 2nd attempt)

You're welcome. Glad it worked. I've read that it's the last ditch effort to revive a dead iPhone (or useful in unlocking) and helped a lot of people. Thankfully I've never had to use it for myself.
