Help!

My iphone 4 has suddenly switched off and will not come back to life.

It has never had a problem before and has worked perfectly well for the enitre month i have had it.

Any advice? why would this have happened?

Does it do anything when you plug it in?

If it's fully charged, try a reset. Close all apps then - Hold down the HOME, bottom button, and the SLEEP, top button, for about 10 seconds until the Apple icon appears, then release buttons. Allow it to reboot, it may take a few minutes, don't panic like I did, wait for it to reboot. Cures many weird problems on iOS devices.
