Activating errors on iPhone 4s and iTunes synchronization troubles

Can anyone help me out on this? I currently have a new iPhone 4s from AT&T and I am having difficulties activating it. When I had it synchronized with iTunes and went ahead to activate it I got an error message stating “the phone could not be activated please try again later”. I don’t really know what is causing this error for I am sure that I followed all the proper procedures. Trying to activate it from the phone also just happened to be a waste of time.
