i tried testing imessage with a friend & it said that it was sent. but when i went to my settings menu, it said that it was waiting for activation, along with facetime. I tried to test facetime but it can't connect as well. i even tried connecting facetime on the ipad, it said that it needs an internet connection to work, but was online at that time. what gives?
Ok. I had the same problem just a couple hours ago and here's what worked for me: Settings--> General--> Reset--> Reset Network settings.
