Ok, I must apologize to those on Sprint who are having data issues after running the energy provisioning...I was thinking you guys must have done something to goof up the data connection, so I flashed the 3/17 cookie ROM, ran the sprint provisioning, rebooted...guess what? NO DATA. It's the ENERGY SPRINT PROVISIONING that jacked up the data connection because it worked before applying it.
Sooooooo, here's what I did to get it working again:
Go to Start--Settings--Connections--Select Connections
Select Manage existing connections
select edit, then next, then next
under username put in your phone number
leave everything else empty
select finish
Data should start back up for you...
Good luck!
