I think
ishare looks more promising, and free.
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 priviledge. I think there must be some free methods to doing that.
