Sharepod/PC - Iphone transefer

[Flame On]

I used to use sharepod for my ipod when wanting to transfer music to it from work (apple doesn't allow syncing of two different itunes accounts with one ipod, because that would be outrageous). But now i'm using an iphone, sharepod doesn't work with it.
Anyone have any soft/freeware solutions they use?
Thanks for any info.

Senuti (http://www.fadingred.com/senuti/) I believe works with the iPhone.

dropbox works great as well.
