What is currently the best external battery for the 3gs? will that work on the iphone 4? because we all know that it still probably wont last a day
Ok so who has the Satechi 5200mah or New Trent 8900mah? and what do you guys think about it. I saw that the Satechi has a compounded interconnection battery which it says is more stable and longer life than the lithium of the New Trent. Thanks!!
