Ask HN: When/Will IOS support file upload?

This is the only hole in my mobile web strategy right now. Apple won't support file upload on the iphone or ipad. I don't want to build an IOS app just to allow users to upload files. I cannot see why they can't come up with a solution for this. My question is will they ever? Searching on the web I can't seem to find any definitive answers as to why they don't allow uploads or if they ever will. Frustrating!
