I was recently trapped on a long long car journey to Leeds with no way to connect my iPhone to the car stereo. After being subjected to many hours of Heart FM and regional radio playing Robbie Williams on a loop I was ready to confess to crimes I’d never committed just to make it stop.

If only I had the AirCurve Window Mount, which combines Griffin’s AirCurve iPhone acoustic amplifier and Window Mount cradle. The AirCurve is an acoustic amplifier for the iPhone 4/4S which can get pretty loud (as much as 25 decibels). What makes it even better is that it can do this without batteries.
