Text Messaging and iMessage not sending texts / not receiving texts on 4S
I have had this problem since I got the 4S. The green and blue SEND buttons are all grayed out, either when sending SMS or with iMessage to another iPhone. The only way I've been able to fix this problem is to do a complete reset of all settings on my iPhone, and you know what a pain it is to redo all of them including my long signature for mail? I have had to do this twice already, and now need to do it a third time!! I have the 64GB version.
Also, I often cannot receive texts from some people using the new iPhone 4S.
Need some help here please, before I contemplate returning this device.
I won't even touch on the fact that the Sprint service is pathetically slow. That's another issue.
iPhone 4, iOS 5
