iOs7

Hi guys!
Just a quick post about iOs7, so far I like it, no real glitch with the installation except on my iPad gen 3.
The problem was that after the upgrade I wasn’t able to use iMessage or Facetime anymore, I tried clearing the users setting etc. Finally I had to restore the entire thing, wasn’t too painful with the iCloud backup, and was sure I would have to reinstall all the apps one by one. It worked surprisingly well.

Now I’m just wondering if anybody tried on an iPhone 4?
