Ok, I'll be opening up a message, read it, then I'll hit, "Reply". When I do, it takes about 30secs(timed) to allow me to type in anything. The keyboard is up, but when you type, its not coming up on the screen, until after its done freezing up. Then, when I type the message, and send it, it freezes right there, on the message I typed, and waits for about 1min! Then, it un-freezes, and sends the message successfully. Its never done this before until recently. I've tried restoring the ipod, reseting it, but to no avail. What should I do?
