I think i may have bricked my iPhone. I've been attempting several tutorials today about unlocking the 1.1.1 version of my phone from the 1.0.2 version i already had. Well now when i turn the phone on... a little USB to iTunes connection screen comes up, then the phone just restarts. I can't even get it to flash a different FW. Someone please help!!!!

Try this...power off your iPhone. Hold down the home key, and then plug in the USB cable. Another way is to plug in the USB cable, hold down the power and home keys then release only the power key after exactly 10 seconds while still holding on to the home key for an additional 10 seconds.
