I just recently purchased my iPad and was trying to find a way to upload files to Dropbox, the same way I can on my Android Tablet.
I came across an app called iFiles.
So far I've been able to upload and download files from Dropbox.
The app also allows me to do the same with my Google Drive and Picasa accounts.
I'm able to upload multiple files to upload, or select multiple files to send off as Email attachments.
It's a paid app, but so far it's money well spent.
