For anyone who has seen the movie, how is she able to do that mind transfer power. Is that something she has been shown to do in the past? Why wouldn't they just make Charles do it?

All very good questions. They should of had Rogue do it. That way they could make some weird explanation that she tapped into a previous power blah blah blah.

I thought all she could do in the comics was phase through things?or am I wrong

And that would have been a thousand times better (imho). It could've also brought alittle more drama to the movies plot if they decided to make Rogue send Kitty back instead of Wolverine, seeing as though they both love Bobby in the movieverse.

That's all she can do. In DoFP comics, Rachel sent Kitty back in time, but I can understand why adding her would've been too confusing for the average movie-goer. The Rogue idea would've been a lot better.
