iPhone 4 SMS not working after JB

[Sgtdag]

SMS on my iPhone 4 can receive only after jailbroken and installed Ultrasn0w 1.0-1. Baseband is 01.59.00. Appreciate any assistance.

My phone has the same problem after jailbreaking. It's a 3G 3.1.3 Firmwear. My texts act like they are being sent but no one receives them. And I never get any texts from any one with any carrier.

Now I saw that my Carrier Data Network was gone so I updated that and got it to come back. I can't figure out what's wrong. Please someone help us

My Sent mms and sms have a RED X next to them. People are receiving my messages but I can not get the X to go away. WHAT is the problem? And the messages are transparent after they're sent
