No accessory = "This accessory is not optimized for this iPhone..."
Immediately after activating my phone and restoring my data, this message starts popping up for no reason I can identify.
No audio from iTunes, video files, or applications coming from the bottom speakers (only available via headphones).
Ringtone, alarms, and regular speakerphone work without any problem.
Never plugged into an accessory device and bluetooth has remained off since delivery...
It's madness...or perhaps a spooky ghost device haunting my new iPhone 4...
iPhone 4, iOS 4
