No luck I'm thinking about downgrading this weekend. iMessage and FaceTime is now I keep in touch with my kids. I only have the IPad so it's important. Friend of mine upgraded his iPhone with no problem yesterday.
I also upgraded my iPhone with no problem - I think that is the most frustrating part. My daughter & son-in-law also upgraded their iPads (same version as mine) with no problem!!
A few things that had helped the Apple Community include these tips:
--going to your settings and resetting your date and time
--changing your wifi settings and chance the DNS to 8.8.8.8
--a RESTORE from iCloud backup.
These seems to be a known problem going on with iOS 7...so hopefully these two things will work.
Will post back if I find anything more.

Today is the launch of the new iPhones. The iMessenger and FaceTime servers may be a bit overwhelmed by new device activations. I'd give it another try a couple times tomorrow if this is your only reason for downgrading.
I had no problem getting them to register on iOS 7 a couple of days ago, even though the upgrade servers were obviously being pushed to and past their limits.
