Best iPhone as Flash drive app?

[Katalysis]

I've been looking for an app to transfer files to and from my iphone. I don't really need the ability to actually open any of the files, just move them around with ease.

I missed the boat on AirShare when it was free. What's the best app out for this and are there any free alternatives?

There is WiFi disk which seems to do the same job as Air Sharing:

I just grabbed FileAid, which is free (for the time being?) and it is really nice. No ads, not complicated, step-by-step instructions on how to share, both over wifi and USB, and for Vista, XP, and OSX.

If anyone else is in the market, I would certainly check it out.
