Is there an iOS app that uploads files to websites? My iPad can only uploads pictures to any website in the browser. My iPad is not jailbroken and I am not planning to jailbroke it. Is their an app in the App Store that can enable me to upload any file I want (ex: PDF, docs) to any website I visit. Their is a app called Iuploader that cost 15 dollars that does what I want but is a bit expensive in my opinion, is their any other app that does the same thing but is cheaper.
iCab Mobile claims to support uploads.

You will probably need to do an "Open in ..." to get it into iCab first.
