Remote control

[ETW11]

Ok I'm pretty sure I'm stranded in left field with this one, but I thought I'd give it a shot anyway. Does anyone know of an app that allows for a phone to be remotely controlled by another phone or PC over a 3g connection without being rooted? And I don't mean just control over messages or something like that, I'm referring to complete control. The reason I ask is because my mother has finally gotten a decent cell phone and understandably there is a steep learning curve for her. I want to be able to help her get out of a bind and avoid frustration when I'm not around. Any help at all would be greatly appreciated.
