iPhone 4 MMS & Internet Help

[iinfamousaznn]

Device: iPhone 4
Firmware: 4.1
Jailbreak tool if used: limera1n
Unlock tool if used: Ultrasn0w
Computer OS: Windows 7
Carrier: T-Mobile

I just bought the iPhone 4 with 4.0.2 firmware, once limera1n came out, I jailbroke it, then used tinyumbrella to update to 4.1 preserving my baseband. So I'm on 4.1 with baseband 1.59.00 and used ultrasn0w to unlock. Everything was working perfectly until this morning when I woke up it says Cellular Data Service Unavailable. When I try go to into settings>general>network I don't see the cellular data network to change out the settings like before. Is there a way to accomplish this? Also my MMS isn't working. I installed one of the packages that would fix it but I guess it didn't. Thanks for your help.

try quickly removing and re-inserting your sim about 4 or 5 time ina row and Cellular Data should sho up.

I had the same problem on 2 iphone 4s but that did the trick

For some reason, when I install TMO mms fix, it doesn't work but my internet is holding. When I uninstall it, my internet goes away.
