Hey guys, i have a problem. I have an Iphone 4 jailbroken on 5.0.1 and it wont send messages, when i try to send a message the mar at the top which slides to right as d message sends just stops at then end and dosent do anything...sometimes it dose send but the bar will just stop at the end... Allong with that i cant recive any texts at all... And when i call somone it just says calling and dosent have the ringing tone its just silent. But the person i call dose get called and answer but cant here me.. And i cant recive calls .. If somone calls me it rings on there phone (it dose call) but on my phone it dosent do anything as if no one is calling me.... Its not got to do with my carrier or anything, ive reset my network settings ... Flught mode, reeboot etc...... I had this problem two dys ago and i tried to re jailbreak my fone and it got half way and stoped and i reebooted my fone n it was fine... I think the tethered boot fixed it oraomething..... Im asuming something from cydia is causing this problem... Pleease help guys... Much appricated
