Hi, I got a strange message today. I've got iMac with latest her of iTunes and iPhone 3g with up to date firmware shock has been synced with the iMac multiple times. Today when I pluged the iPhone in, rather than syncing, when iTunes opened and I opened the phone Fromm the list of devices on the left the spinning rather than opening with the usual tab selections there was just a large very box with the word in a large font: "congradulations, you have successfully unlocked your iphone." I clicked ok and iTunes then opened as normal. What's this about?
