As prior warpers already realized from those forums I am a battery power nutjob. I just don't like strings attached! I wanna use my device, and then when I'm ready to lay down it will get plugged in. Anyhoo, surfing the plethora of extended batteries for the galaxy s2 on the interwebz one will realize just how many versions of the s2 there are. I know this device is extremely similar to the epic touch 4g. My question is, do the epic touch 4g extended batteries work with this phone? Are there any others? Search queries with "boost" added to the algorithm leads to minimal results so i figured I'd come here. Thanks in advance!
