Okay so I've been messing with this all day. Used redsn0w to jailbreak and install cydia+ipad baseband then I installed ultrasn0w and it finally recognized my Sim card. Everything seems pretty chill except SMS doesn't work at all. If I send a normal SMS it just crashes but if I send a iMessage it just loads forever and if I go to my settings it tells me that iMessage is "waiting for activation..." Does anyone know how to help me? I followed this tutorial, http://www.youtube.com/watch?v=LNo0DIUN0b8 , and I'm having issues. Currently reinstalling the iPad baseband through redsn0w to see if that fixes anything. Also when I try to jailbreak with Install Cydia+Install iPad the fetching iPad files makes the program close so I installed them separately. My phone is an old bootrom. EDIT: Jailbroke and installed the iPad thing+ultrasn0w but when ultrasn0w finished installing it gave me "could not activate cellular data network" and still everytime I try to text it crashes. can someone help?
