I've had stale clients and have deleted them, but I can see no association between stale clients and the locking. It's a complete freezing of the iPhone app and it isn't even possible to exit by using the home button. You have to switch off the phone.

Incidentally, I do appreciate that we're still using a pre-release version and that we can't expect everything to be perfect. I think all these comments are intended to be constructive in helping you develop the best possible sync solution.
