Hi everyone, i have iphone 3gs iOS 4.0.2. its jailbroken and unlocked. i've the "Call Ended" problem. i surfed lots of forums and a lot of google.. nothing seems to solve my problem. my configuration is as follows: settings->general->enable 3g = OFF settings->general->date & time->set automatically = OFF settings->general->date & time->timezone = SHANGHAI settings->phone->show my caller ID = ON settings->phone->call waiting = OFF settings->phone->call forwarding = OFF Push notifications-> OFF i've restarted the phone many times. nothing seems to be working. another noticeable thing is that the Signal bars is showing only one bar. but i cant receive calls, cant make calls any help would be appreciated SBSettings and lockinfo were behaving little nasty for last 1 day or so.. i've uninstalled both of them. one more thing: settings->general->about shows the correct carrier name which is "China mobile" plz let me know if u know any other details.
