Sprint TP not connecting to internet or receiving MMS

[DarkDragon]

I cannot connect at all to data (internet, MMS, update weather etc). I have flashed back to stock and still no go.
I was on Psyki ROM for a few weeks then saw the Energy ROM with Sense and switched to that. It started not working with that ROM. Flashed back to stock, hard reset twice, and still no go.

I called sprint, and they tried to have me enter the MSL, which didn't work either. They said that I would need to take it into the sprint store for service, but I don't have the time with the holidays and all.

I am currently on the stock sprint rom, but am going to switch back to the Energy ROM.

Any ideas why I cannot connect? Did my settings get screwed somewhere?

Thanks!

I checked settings > connections > connections and went through the connection settings and they are blank. If anyone knows the login for phone as a modem, that would help, the user name, password and domain are blank, but #777 is ok though.
