My iPhone 5S is now effectively an iPod, which is what I expected. I plan to keep it for development purposes. What I did not expect is iMessage to be all messed up. It says 'Waiting for activation...' in Settings. I've tried re-signing in and all. Messages fail to send. Up until I disabled SMS and MMS it would try sending as SMS too. Does it not realise there is absolutely no non-Wifi connection now? Do I have to take out the SIM card for it to realise? Obviously I do not want to restore because it is jailbroken on 7.1.2. Everything else is working.
