I use my phone a lot and i mean a lot! I am considering these batteries.I wouldn't mind the extra thickness if the 3500 is that much better than 1750. What i am worried about is,where could i get a bigger back plate to accommodate the thicker battery.Do they even make these? I've looked around some but haven't found the info yet. Anyone here have any experience/comparison or pics of the 3500 Thx!
