Just wondering if anyone has tried the extended 2600 or 1600mAh batteries by Seidio for their CrackBerry? They say the 2600 has 140% more power then the standard battery and the 1600 is like 35% more charge, seems like a great deal but is this a reputable brand and has anyone ever had any issues after using one of these batteries? Other then the custom back for the 2600, which looks kinda ugly....
