Seems there is quite a bit of interest in the mophie Juice Pack 3G for the Apple iPhone 3G, as mophie has posed a Q&A page so prospective customers can ask those all important questions.
Some of the questions being asked is when will the Juice Pack 3G become available? Well the answer to that is mophie will begin shipping on the 30th of October, but you can pre-order if you wish.
Another is, can a user sync an iPhone, iPod Touch or iPhone 3G while the Juice Pack 3G is connected? The answer to that is yes you can sync and charge the iPhone 3G and iPod Touch while still connected but the “Pass through connector” is for the first-gen iPhone which isn’t supposed to sync.
