I have the Parrot CK3100, which worked perfectly with the iPhone before 1.1.3. Now when it starts the phonebook sync, it eventually locks the iPhone. When I say lock, I mean iPhone is unusable (screen is off or frozen) and can't receive calls until I hold the home button and power button until it restarts. I've called Apple support, tried restoring the phone in iTunes, unpaired the devices, reset the network settings, re-paired the Parrot, and no luck. It occasionally just doesn't connect to the Parrot, but usually just locks up the iPhone. FYI, I have tried using a friend's Nokia (with Bluetooth 2.0), and the Parrot (with phonebook sync) worked perfectly. So the Parrot isn't having any issues. I've had these iPhone and Parrot working for about 6 months without a single issue. I'd love to go back to 1.1.2, the car kit does a lot more for me than locate me or changing the home screen icons. HELP APPLE, it was perfect before the update!!!!
