Hi guys, I'm in the mood to buy a battery pack for my iPHone 3G. Looking around I found these two: Kensinton battery back RichardSolo RS001 Anyone own one of those? Do you have pros and cons of each one for me? I prefer the RichSolo design but I think having a cable between the battery and the iPhone (like Kensington has) is more convenient specially when you want to charge and you the iPhone at the same time: something I plan to do. Thanks and have a nice day!
