I've noticed on my iphone 4 with iOS 6 and the latest updates sending texts to iOS devices and even non-iOS devices theres frequently a delay in sending a message it will get all the way to the end and then just sit there, if i need to reply it will queue up the messages.
is this an iOS issue? carrier? seems rather flakey compared to iOS 5
