You've all seen the evo/touch pro 2 battery swap. After I saw it I did a little research. OEM HTC Touch Pro 2 (CDMA) Verizon Extended Battery - eBay (item 310229048973 end time Jul-23-10 10:37:37 PDT) This is what I came up with, a oem 2150 extended battery for 30 bucks, its basically the same one that Verizon is selling for the incredible for 80$. I ordered it today and the only problem ill have is the battery door. My solution is to use the innocase 2 or a silicone skin without the battery door. I might even cut my stock door in half right below the camera opening so if I use the innocase it will look stock from the back. The reason for all this is really like my innocase 2 so I don't want the 3500 and the 1750 really doesn't do much. I'll post some pics as soon as it gets here.
