After watching the demo video of mobile me it says you can share large files with your iphone, along with photos calendars etc. My question is what kind of 'large files' (idisk stuff?) could you share and open with the iphone besides pdfs? I often sent class notes to my ATT Tilt to study in class. But if the 'large files' are what im thinking of (text, numbers docs, movies i guess, and what have you) how will i be able to open these in the iphone?
