hi, guys:
i found a online service called dropbox that like mobileme, which gives you 2G storage space and with faster upload and download speed (i feel)。 The more exciting part is you even can log in by iphone to view uploaded file and watch movie or listen to music.
Here is the link

Dropbox is a single file-sharing service, and a direct comparison with MobileMe does not take into account all else MobileMe does. Still, I do use a combo of Dropbox, MobileMe and YouSendIt to share files...all work great for me.

Thanks for the link.
