Wait... maybe that's not quite the same thing... TVersity is closer I think, although it does what My Files doesn't do, stream media to your iPhone. telekinesis does something similar to TVersity. Also Free.
Ok, I guess I'm missing the mark. My Files to iPhone basically makes your computer open a file and it takes a snapshot of that file and allows you to view the PNG of that snapshot in Safari.
Sorry, I wouldn't pay for that privilege. I think there must be some free methods to doing that.
