iMessage says it was "delivered" but recipient is not receiving my iMessage...
My iMessage will send and say "delivered" but receipent won't receive my messages at all. I tried rebooting my iPhone (home/sleep button) and it hasn't helped. What can I do to fix this? Are there any settings that I should enable/disenable? This started to happen on Wednesday...I was on a plane and put my phone on "airplane mode" via homescreen short cut. Don't know if it's related?
