Well after manually updating to froyo, I have noticed that my 4G speeds have increased. I live in an area that could barely get signal and was averaging about 1.5 mbps. I'm averaging from 2.5 to 5.5 (max) where I live. IDK if Sprint just opened the 4G floodgates or if 2.2 has given the radio more bandwidth to play with.. Just wanted to state my experience in TX. Anyone else noticed better speeds? or worst speeds?
