iPod touch generation 4 iMessage won't activate.
A day or so ago I tried to go into my iMessage and was greeted by a screen with a "Get Started" button on it as if I hadn't set up iMessage already. I promptly tapped the button and it asked me to enter my apple ID. (it already had my email address entered for some reason) After signing in another screen asking me which email I wanted to use popped up and I selected the only email I had associated with the apple ID account. After hitting 'next' it said 'Verifying' with a loading prompt next to it, after it says this for 5-10 seconds it confusingly goes back to the sign in menu I saw before. Nothing has changed and when I try to log in again it does the same thing.I can't get into iMessage which is exceedingly frustrating. I am on the latest version of iOS that is available for the 4th Generation iPod touch (iOS 6.1.6) and this happened totally out of the blue, I did nothing to the device except regularly using it prior to the problem. I have turned the device on and off with iMessage and Facetime off (it is doing the same with facetime although I rarely use it) and I have even reset the device out of desperation. I have called apple support, searched on the internet for many fixes which I have tried (obviously none of them working) and now I am here. Any comments or input is greatly appreciated. Thanks!
