iOS7 GM has been released to Developers this evening. A few nice things in there – lots of new wallpapers, ringtones and alert tones. Everything is a lot more polished than the last Beta. And so far, all the apps seem to work. Still annoying that, even though your most recent backup wasn’t created all that long ago, the update and sync still loses most of your installed apps and music – mine had pretty-much all disappeared and I had to re-sync everything again.
