IPHONE 4 6.1(10B144) jailbroken. wife is calling and all I get is a regular "ding ding" bell ring tone. but my regular ringtone is the "harp" I didnt do anything with the phone. I didnt install anything and shes getting pissed and rightly so. can I reset something in the phone? she says shes calling and after one ring it hangs up on her with the "du du du" tone. so she texts me to call. we are on two different mobile suppliers. I called from another phone (from a different 3rd supplier( and its ringing and showing up on my screen. I also get delayed text messages from her. sometimes 2 hours after. not sure what to check to see if its the issue. do not disturb is off. sounds as normal. 3g/data on. airplane off..duh. but not sure what I can check.
