Hi. I've been looking for a battery backup for my iPhone 3G. my price range is about $70 or lower, unless there is an amazing product for like $5 or $10 more. The lower the price is better. I need something that will last about 8 hours with 3G usage and video playback. Around 300-500 mAh. Before anyone says so, I searched the forums but nothing was what I wanted. I have already researched for about 3 hours now, and found the Imax, RichardSolo 1800, and the RishardSolo iPod/iPhone thing. I don't really like the look of the Imax, but if there is nothing else, I will go with that. The RichardSolo's aren't powerful enough for my needs. Again, the lower the price the better. This won't be a daily use thing, mostly for vacations and road trips. P.S. Does anyone know if there is a prepaid SIM card that works in England, Germany, France, and Italy and if an unlocked iPhone 3G works there? This probably should go in the main iPhone forum, but I don't wanna start another thread just for this. Thanks a lot in advance! I will really appreciate the help!
