How's the backward compatibility of iOS 7?

[Cougarcat]

Three of my apps that I use regularly--Imo, Dropbox, and Pulse--all have minor or somewhat annoying UI glitches. The UI is so different that there are a lot of minor things that need to be fixed, like the iOS 6-style keyboard. And of course, apps need to be updated to use the new backgrounding feature. I hope to see a lot of updates coming in after the 10th.

I've had a few app crashes since using the betas (BBC News is one example). As said its down to the devs to figure it out, and they aren't going to release an iOS 7 compatible app until its launched.
