    Ok, I have an iphone 3g which now has the stock 3.0 firmware. I was using an unlocked version of 3.0 when randomly it started doing a reboot loop. If I plug it into my computer it will work like its supposed to but the power/sleep button doesn't work right. I can put it into recovery mode and I tried to restore using a custom 3.1 firmware i made with pwnagetool, that didn't work. So I tried it again and made it a new phone, that didn't work. So I tried to just go back and install the normal 3.0 firmware, and it still does it. I use this phone for everything, and I live in Italy so I have to used an unlocked iphone. Any ideas?

    EDIT: So I was able to turn it off. When I plugged it into my computer it started working and came up with slide to turn off so I did to see what would happen. When it shut off, it just started the reboot cycle again. How is that even possible?

    It does sound as if you might have a hardware fault of some kind in the power on/off switch. Is it still under warranty? If so I'd take it in for repair/exchange
