I know there was an outage yesterday, BBM and all other BIS... have you been able to log in and change your device info on Sprints BIS site?
I may be repeating a step, but you may be able to get your service books in and that might help. Cycling the radio off and on, doing the HRT registration from a point further down in the table, the only other thing i can think of (outage not considered) is possibly an authentication issue with your carrier. CDMA can have a problem with that, but i dont have Sprint so I wouldnt know where togo fom there.
Hope you can get rid of paper wieght mode soon....
