what you just witnessed was a OTA PRL (Over The Air Preffered Roaming List) update, now for some reason it always errors people out when its done this way, the update goes through but it always errors out in the end, there is an alternate way of doing this, and thats by going start>settings>system tab>update PRL and that'll do it too, this is assuming your using the stock sprint ROM of course, hope that helps!
