Stopped receiving SMS on phone when using @messaging.sprintpcs.com

[Mofo2713]

I have a TP2 service with Sprint. I have upgraded to WM 6.5 official release on the 19th. Everything was working fine and then last night around 11PM, I stopped receiving SMS. I receive many (50-60) SMS/day due to mostly auto-forwarding from Gmail. I am still able to receive mail on my phone just fine and text messages from other cell phones come through no problem. Only problem I have is when I send something to @messaging.sprintpcs.com it doesn't come through anymore.

Called Sprint and of course they didn't tell me anything new that I didn't try on my phone already on my own. It's just like it stopped working all of a sudden. I haven't installed any new programs from the time it was working last night until the present or have made any other adjustments.

Any advice/suggestions would be greatly appreciated.
