According to the masses of android users, they're not experiencing any problems at all and the network issue is iPhone related only. I don't have sprint, so I couldn't speak for it either way.
I wouldn't say things are all rosy. I have noticed a significant drop in speed on 3g in Atlanta, Miami and Chicago over the past year on my EVO. But nothing as bad as the new IPhone users complain about. But it is enough of a drop to cause notice to me also.
