Hi I have just started with IOS devices and reading about WIFI tel and text coming out with IOS 8 so thought I would look in here to read about it, and fine IOS 8 is already out or am I missing something. I checked my phone and iPad both running IOS 7.1.2. Question is how do some have the iOS 8 and other don't both my devices say software unto date. Do apple restrict the updates??
