Use a different browser. iCab Mobile supports uploading, downloading, and side-loading to DropBox or iDisk. The only time I use Safari is when I clock a link in Mail or Twitter or some other client; otherwise, I use iCab almost exclusively.
while i use icab 99% of the time, i've hit a few limits. first off, not being able to set it as a default browser is frustrating. secondly, i've found a few rendering differences between it and safari: onswipe (the tablet theme powering wordpress.com blogs) and google font api being the two biggest ones i've ran into recently.
Too bad they can't be bothered to put any pricing information online. I have a project that needs an editor, it looks really good, AGPL is not even kind of an option, and I'm willing to pay for a license. But heck if I want to deal with "contacting" somebody to start thinking if it's worth looking at.
