iOS 8 - Installation FAQ's / Known Bugs / Errors

It looks like this sub is getting filled with people asking the same questions over and over again and everyone keeps downvoting the repeated questions so some people are getting no help at all.

I think it would be a good idea to have a sticky post with all the FAQ's, known bugs and errors users are seeing while upgrading their devices.

Here's some FAQ's i've been seeing all morning.

• Do I need to register my UDID to get the iOS 8 beta installed? Yes, you need to have your UDID number registered as the installation will activate your device and it will look for your UDID on the Apple registration servers.

• How do I register my UDID without paying the $99 for the developer account? There's a lot of ways to do this, I personally went to eBay and ended up paying $5 dollars to register my iPad Air and my iPhone 5. If you do choose this path, make sure the seller has positive feedback and make sure this is recently created account (to avoid scammers)

• Where can I download iOS 8? I personally used this site for both of my devices LINK

• Will all my apps work with iOS 8? Here's a post created last night which includes names of apps people already tested

Known Error #1: Make sure you disable Zoom under accessibility options as it will crash your activation as stated on this post

Known Error #2: Your Google Chrome WILL STOP WORKING as stated on this post

Known Error #3: People with iPhone 5s are noticing their phone is getting extremely hot as stated on this post

It also looks as the iPads are not getting all the new features immediately (just as it happened on iOS 7 beta). There's 2 other people besides me who are not seeing the new features on our iPad Air.

Let me know if something in here is incorrect and please give me feedback in case you think something needs to get modified/added.

Thanks!

EDIT #1: I'm gathering all the most common reports on this thread to add them in here, thanks for the great feedback everyone!
