So you've already done an ESN swap on Sprint's website to activate your backup 6700? ##778# is the main programming code I think, though you'll also need your MSL code to make any changes. (you should have gotten that on Sprint's website during the ESN swap) ##3282# is for setting up data services, although I don't think you'd need to change any of that - the phone should try to provision itself once you attempt to use the data connection.
