IOS 7 beta 6 iMessage and FaceTime?

So I got ios 7 beta 6 for my iPhone 4S and I'm trying to use iMessage and FaceTime but it asks me to sign into my Apple ID but after a while it says an error occurred and to check my connection. But my connection is fine. Why is my Apple ID not working for the FaceTime and iMessage activation?

Assuming that you have your device's UDID registered with the Apple developer center, then it's a matter of waiting for the activation to complete. It can take time, and I'm not sure if/how the recent developer center issues may affect this.

Is your UDID registered? A lot of people have reported problems with activation when they install iOS 7 without registering their device's UDID with a developer account through a site like http://www.udid.in/.It's $5, and then you also don't need to worry about Apple disabling your device for running unreleased software.

Register your UDID at www.udidregistration101.webs.com and they can help you get your proper IOS 7 download links and as well help you get IOS 7 onto your iDevice. They will register you within 10 min.

I'm the developer and this is my website. I can help you get IOS 7 on your iPhone and as well get it up and running smoothly.

As well I have a video here:
