My iMessage has been broken, probably for a month or two, I finally noticed it, since most of my friend are on Android or dumbphones. I can go into settings and enable it, but soon as I go back into the settings, it disables itself. I tried enabling it on the iPad as well, and that doesn't help. The iPhone is a 64GB on AT&T, 5.0.1 Jailbroken, and it has the camera disabled by the carrier through parental controls (for work, a US DoD contractor). It's not a huge deal, as everyone I know with the iPhone has unlimited anyways. I just like showing up blue for other iPhone users and getting read receipts and such. If anyone has any ideas as to why it's not working, that would be great.
