I don't know what exactly do you mean. I used Jumpshare, CloudApp, Mediafire, Droplr, Dropbox, Huddle and I like all of them (specially Jumpshare and Droplr). Anyway, those are to UPLOAD things and share them if you want.
I use Dropbox for my some stuff which I want access to across multiple machines, and the Apache web server which comes with the O/S to share stuff with others.
If you don't need more the 2Gb, Dropbox is what I find easiest. Apps for most devices, plus every time you refer someone you get an extra 500Mb, this can go up to 16Gb.
