Just a Little question I'd like to ask..
Is their any simple way I can downgrade from OS5 to OS4.7? Or an upgrade from 184.108.40.2061?
And also, if I was to change OS version, would my BlackBerry lock itself back to its default network? I was on Orange but I got my bb unlocked so I could go on o2..
