"This accessory is not optimized for this iPhone" Error warning.
I am getting, at somewhat random intervals an error message (see above) it continues with "you may experience interference (etc etc)"
The warning appears even when nothing is connected to the iPhone and if the iPod function is active it stops the music. It also appears to reduce the battery run out time. I have already installed a new battery (1600mah) but no change.
Any ideas what this could be?
Is this a good question?
