at some point I will figure out how to do this and will release a free app for it, I'm tired of having this option, not a standard option on blackberry.
There already is a free app for it. just google orientation lock. Took me a while to find it, but all it does is add a global lock to your menu. Press the lock button to lock in whatever orientation you have the phone in, press the menu key again to unlock it. simple as that.
I liked six tools a lot for this function but with subsequent OS updates, six tools has become way to buggy for my liking(screen blanks out when potting it on the cradle, menu wouldn't come up while on the cradle, and just general bugginess I didn't even realize was sixtools until i uninstalled it).
