I've heard that eBay and Dropbox are two other apps that have major issues with iOS 7. I've downloaded it but given the number of bugs I've heard of I'm not yet game to install it as there are too many things I rely on my phone for...
Given it is for developers, wouldn't you install it on the phone you use for developing and not the phone you use every day?
Still waiting for a AFF live tile on my WP8 and Windows RT Tablet

Whilst i'm using iOS 7 legitimately, developers are gagged under NDA from discussing specifics.
