JTLX just purchased this after getting an iPhone for Xmas-it broke my iTunes 7.5 making me Force Quit 5 times and being unable to restore the iPhone. This left me with an iPhone that would not boot without the "connect to iTunes picture". I had to use my iMac to restore the iPhone and then re-register it on my iBook. Not impressed and don't think I'm going to try it again $25 wasted it seems. I followed ALL instructions to the letter until iTunes froze and would not let me Restore.
