Jailbroke with jailbreakme.com and used the Gevey Ultra to unlock since I am on firmware 04.10.01 but I cannot send SMS or MMS but I can receive SMS through my carrier of TIM. I have tried downloading iPhonedelivery with no success and I don't have FuriousMod installed, everytime I put that on the phone won't get a signal. So all I have is the Gevey Ultra SIM card with Carrier SIM and Cydia. I can have a signal but nothing allows me to send and receive SMS or MMS (the button doesn't appear). Should I consult my carrier or is there anything else I should try first? Anyone have any suggestions?
