It's fully updated as far as iOS goes. I was on my run today and literally it just stopped working out of nowhere. Looked online for troubleshooting but Apple doesn't help AND I don't wanna screw my phone up any worse (whatever is going on) by doing something to activate iMessage again. Anybody have a proven trick that may help me get this back on track? Much appreciated!
