A company called Beeweeb (http://www.beeweeb.com) are working on an application called Beeweeb Mapper Mobile (http://www.beeweeb.com/products_bwb/map_mobile.html) which allows online file storage which can be shared with colleagues. Although aimed at the business user, I'm sure that non-business Normans like me could find a use for it also....

You can get the user documentation from here (http://www.beeweeb.com/pdf_bwb/man_mobile_eng.pdf)

great. It's perfect to save files remotly.
I think it can be useful to access to my own files from everyplace in the world.
You can also access to your space by a normal PC so I can always get all my photos or sounds. :D
very good product, one of the best for my 7650
