iMessage frozen/crashing I have an iPod Touch 5th gen and I sent a really long emoji message to my friend and both our iPods froze! Now everytime I try to open it, it goes to the conversation menu, freezes for about 10 seconds, then crashes back to home screen. 

I tried:


Restart
Long Restart
Double clicking home and closing all recently used apps
Turning off imessage then turning it back on and logging in
Going to contacts then clicking to iMessage them


Nothing works.
I just had the same problem. After seething my iPad and restoring it through icloud I still wouldn't work but what did work was going to a random contact and clicking send message, it opens iMessage right up and I was able to delete my conversation that was causing the problem!
