Ios7 Imessage and Facetime activation bug?

I have a question regarding ios7. I recently got my iphone 5 to update from io6 to 7 a few hours ago after a day of endless failing to do so, so now that everything is set up, I can't connect to iMessage or Facetime, which is strange because I know for a fact that it was working with ios6 yesterday. I have tried, pretty much all day today to sign into my Facetime and Imessage but I keep getting "Could not sign in, please check your network connection and try again". There's nothing wrong with my network connection, my Wi-Fi is fine. I then try to go to settings and all it says is "Waiting for Activation" on both Imessage and Facetime. Is this a problem on Apples end? Because not only am I encountering those two problems, everytime I open up an app, such as facebook, kik messenger or a game for instance, a notification pops up and tells me that I have to connect to iTunes in order to get Push notifications. Anyone else having this problem with activating their FT and Imessage? As well as the Push notifications issue? Any tips or tricks I can use to Activate my Facetime? All answers would be appreciated.

I'm having the same problem with itunes:/ hopefully apple will fix all the bugs soon…
