I have a T600 on the Sprint network with the recent upgrade installed. Despite all this talk about SMS working here in NYC, I still find that if I SMS a person with a message-enabled cell phone on another carrier's network, it can take, literally, days for the message to arrive on the other person's phone. Forgive me if this has been queried before, but is this kind of inter-carrier time delay supposed to be the norm even now after Sprint has presumably gotten its SMS working in NYC?
