Still no nice way to change user agent on closed PR1.3 device, is there...?

Just tried to change UA on my wife's N9 which is not in open mode, and I ran into no end of trouble... got the device locked up but of course that is no problem to fix.. anyway the grob changing is a no-no-solution, imagine if you have to boot the device for some reason while on the road and it ends up locked again

There would be hell to pay, literally!
