Hello My ipad imessages won't deliver. It gets stuck in the last stage (after about 70% completion) and then after a while the not delivered message comes up. Everything else is working fine, safari, games etc. why is this and how do i solve the problem? I have tried turning imessages off and restarting my ipad but it makes no difference. I havent tried resetting the network settings as i cannot remember the passcode (is it different to the cover code?) and i don't know how and where to recover it from? I would really appreciate it if someone could help me out here. Thanks!
