I've installed this app yesterday and everything worked fine except the application , so I purged it because it was useless . I think I rebooted mine ~5-6 times so far after uninstalling AIRUI but I didn't get any error message . I do not have security code , not even PIN .

Now I realize how lucky I was because just yesterday my new N9 arrived after 3 weeks of being in service (random reboots problem) .
