I have a sprint samsung epic 4g. I endlessly waited for the 2.2 update, but got tired of waiting. So, i heard of this manual way to install 2.2 froyo, which i was told was the official update, which it was not. So i installed it, and its glitchy and all, but im okay with it. The thing that worries me is, will i be able to get the legit update when sprint puts it out?
