I have a iPhone 4 from USA. When I was there MMS was working fine when I came back to Saudi and unlocked my iPhone through ultrasn0w MMS stopped working no matter what I did any setting I input I does not send at all??????

APN: jawalnet.com.sa

MMSC: MMS ??????? ???????? ???????

How can I fix it cause I think the unlock is causing the problem and I cannot restore causes it is not factory unlocked????

Its on 4.0.1 and my friend is on 4.1. We have the feature for sending MMS but when we send it does not go through??????? PLEASE HELP.........
