How can I reset my iPhone 1 without using the (broken) power button? The power button on my first-gen iPhone is broken. I remember last time I came across this problem I found a utility (for windows) which caused the phone to reset to enter restore mode (the one with the yellow alert symbol), but I can't for the life of me find it again. Does anyone know what it is?

Thanks for any help,
Wyatt.
I don't know about the yellow alert symbol, but a quick google for "iphone recovery mode utility" revealed RecBoot, which looks like exactly what you're looking for.

Also, Settings > General > Reset > Reset Network Settings should restart your iPhone.
