IPhone :: Imessage And Factime Not Working?

As I'm sure all of you know, Imessage and Facetime seem not to work with new IOS 5 updates.I can't seem to understand why, but it seems as if pre-paid users of the Iphone are the people whom are suffering the most. If your anything like me, your able to send imessages and use facetime via e-mail, but that kind of defeats the purpose of having an IPHONE.After countless hours of research and trying little stupid things in settings, I have found my solution. Sadly, this does require a credit card, as well as a purchase of an application (any 99 cent app you want). I personally hate this fact, however it did work for me.The steps I took are simple and are as follows.1. Go to settings, and select your store tab2. Tap your apple id and select "view appleid"3. Edit your payment info by adding a credit card (if you already have one simply add a new one and delete that one)4.Go to the app store and select ANY 99 cent purchase.5. voi la, my imessage and facetime activated within a matter of seconds after purchasing asphault 6- adrenaline rush (or something like that)I am using Rogers pre-paid canada and this method worked for me even using a United States apple id. Another FYI is that it never hurts to have about $5 in your pre-paid account at all times.

iPhone 4, iOS 5.1.1
