You may remember the Mophie Juice Pack from when it was originally released for the 1st Gen iPhone.  Well come September you will be able to get the 3G version of the Mophie Juice Pack.

Right now they are taking pre-orders for the case.  Likely it's not going to be all that different from the original version of the case. So if you're curious about it, you can read up on our review of the original case that was posted back in April.

It can extend the internet browsing time by up to six hours, audio playback by up to 28 and video by up to eight.  The cases will cost you $99 a piece.  However, it'll still be September before the very first shipment.
