Hi guys.
I have been loosing my mind on this problem for a while testing on 2 different iphones 4g both running ios 5.0.1 There is a definite issue with imessage and facetime when jailbroken.
I have restored and started over on both phones a total of at least 7 or 8 times. Imessage can send pictures initially from both 3g and wifi. facetime also works fine on wifi. After i used facetime to test (make a facetime call, receive a facetime call and attempt a facetime call while on 3g and get the message saying that it requires Wifi) i did a reboot. Immediately, imessage can no longer send pictures. It says its delivered but in fact, it never made it to the recipient. Facetime, also starts freezing on connection from this point on.
Disabling iMessage and re-enabling does nothing. My ipad 2 with a factory ios5 works all the time for both imessage and facetime. This seems to really be jailbreak related. The only apps i use from cydia are: sbsettings, inotifier+, anyring, installous and infinidock. I haven't tried a jailbreak without any cydia apps installed but i seem to be able to reproduce the issue at will. A few facetime calls and a reboot usually messes things up.
If anyone has similar cydia apps installed, pls let me know. Im curious to know if this is caused by the jailbreak itself or by a specific app. I have spent so much time on this that my brain hurts...
I will post an update if i find out more. Please do the same if you have additional information. All i know for now is that there are practically no posts on this issue yet this problem is very real.
