Actually it's looking more and more like a G5 update issue as my own profile now has "null" device entires as well, and I'm on Android. However, I've just tried reinstalling my own game, having backed it up first, and I was still offered a restart at level 362, so it appears the G5 servers are now just holding our device ids elsewhere. So I conclude there's nothing wrong with your iPad.
