iPhone 4S Comm Center crash/signal drop solved!
After much reaseach, 6 iphone 4S, and reviews of other people trying to figure out why our iPhone4S' are suddenly crashing, then going into a terminal boot loop, it's this:
MMS from Android phones. Any carrier. Something happens inside iMessage or TXT trying to fetch the MMS, and it causes Comm Center app to crash, and the phone has to be restored.
This happens on all carriers, all Android platforms.
Props to the community for figuring this out, and boos to Apple
When your phone starts to crash and lose signal, look insider your settings under general then "diagnostic" and you will see "Comm Center" crash over and over again, more and more rapidly. It's still trying to fetch the message.
turn off MMS=no more problems
try it, report.
iPhone 4S, iOS 5.0.1
