Today I am looking at the Mophie Juice Pack Air for the iPhone 3G and 3GS smartphone. The Air is a case with a 1200mAh battery inside to extend the run time of the phone while protecting it from scratches and drops.

The Air has an on/off switch and other features that make it easy to use and it adds little bulk to the phone. The Air is available in white, purple, and black colors.

Today I am going to look at the Mophie Juice Pack Air for the iPhone 3GS. Read on for all the details on the Mophie Juice Pack Air." Read the full Mophie Juice Pack Air review here.
