My iMessage isn't working. It says I'm connected but it will only allow me to text.
I've been using the new iMessage since the new operating system has come out. But today it stopped working. I only have one friend with and iPhone, so I can't test it out between myself and anyone else. I went to my settings to check that I am able to use the iMessaging system. I've been texting my friend a few times today and it's just regular text. The green bubbles instead of the blue! It's really frustrating, I don't understand why it doesn't work. Please help me out!
iPhone 4, iOS 5
