There are several iPhone battery packs, and I haven't seen one I really liked yet, but I DO like the idea battery than the idea of swapping batteries. I like that you have the choice of thin-and-powerful or bulky-and-powerful-and-long-lasting! (But still not that bulky compared to most smartphones--with their smaller screens and poorer 3G battery life!)<br><br>I'd want one that clips to the back with only minimal bulk at the top/bottom/sides--just enough for a dock connector. A hole for the camera of course. And I'd want it to have its OWN dock port pass-through (all pins/functions) so I could charge it with the SAME able whether using the pack or not. Most batteries seem to need their own USB cable.<br><br>nagr[color:red]o</font color=red>mme<br><br>I require stroyent!<br>TeamMacOSX.com | MacClan.net
