The gous over at The iPhone Blog has published a review of the Seidio Innocell External Battery Pack for the iPhone 3G. You can find their review here
<blockquote>Final Thoughts

It's light to the point of feeling a un-real (what you want in a carry-around), re-charges your iPhone 50% plus (what might not be enough for hard-core conference/event goers), and does a pretty good job of walking the middle ground between case and dongle.

The one complaint I have is the lack of a dock-lock. While the design and fit is excellent, if I have to use it on-the-go, I want the security of knowing it's not detaching unless I detach it.</blockquote>
