My friend had the same problem, it's working for him now. Not sure if he just left it to 'activate' by itself, though.
I've got the 4, and had to delete quite a bit of stuff to make room, so not sure if iOS7 is worth the large chunk of memory it's taken up. It looks pretty slick though personally, and I had fun with the new ringtones too.
