After Jailbreaking with purplera1n, and installing ultrasn0w,
Everythng works great, but when I reboot the iPhone, the iPhone won't call.
It will stuck on "Calling..."
Only thing will solve this problem is I have to remove the sim card and put it back in.
for the time being, I am doing that, but today I couldn't find a paper clip, so I was screwed
Any suggestions?? any one else having same problem?
