Just came across this on eBay. Anyone have any experience with one? Surely 3800mah is an overestimate, but I fared pretty well with a generic battery for my Evo. Definitely kept the phone going a lot longer than stock. For $10, free shipping, and a backing, I think I'll be the guinea pig on this one...
