hi guys, i have problem with my jailbreak iphone 4. i jailbreak my iphone 4 from 4.3.3 to 5.0.1 by using redsnow B1 last time and everything seems to work fine, but recently im unable to receive call, call out, msg or anything that is related to mobile carrier. i had rejailbreak using B4 (no restore) just now but problem still cant solve. does anyone facing the same problem?

paid~mine is family line, my dad's line can use no problem, the problem now is like when u calling someone, it will stuck there. anyone having the same problem?

i had done a jailbreak without itunes just now but it cant work! and after i install itunes only it work

as in for example, i tried to call a number, the screen there indicate "calling XXX..." then the number that i called the phone rings and i answer with that particular phone but my phone still in "calling XXX..." and there is no tone and i cant hear anything! case 2: i tried to use other phone and call my phone, there is calling tone but my phone dont ring! and i cant send sms or rather receive sms from others

thanks for the info, do a fresh restore as in restore it with custom ios5.0.1 ipsw that manually download? do u experience it from the moment u jailbreak or after a period u jailbreak? mine happened just recently, before that was working fine. p/s i jailbroken my phone on december 2011 once the jailbreak is out
