understood that all, just put that question mark by accident standard procedure in other (Android) phone: find out ROM + root method of the day - install security software (LBE style) - find some software that allows side-downloading APK from ecosystem - install (side load) essential apps on mobile device - fix per app permissions on mobile device - hope all works as it should - suffer inferior user interface - never update because of not wishing to repeat the whole **** over and over - wonder about security leaks... -->>> big headache, no thanks.
