Iphone won't turn on!

[Peterre]

Hi I'm using an american iphone with jailbreak here in Austria.
But after an update with itunes 8, it won't turn on any more.
Seems to be dead.

Is there anything I can do?

If you plug your phone into your computer and while in iTunes hold down: F, R, L, Q, and 7, then unplug your phone really quickly and your problem will be fixed! I had the same problem but this did the trick

Are you sure this works?
Which itunes version did you use?
