The one thing I want is file management. Be able to download files through safari or email, add files directly from a computer (not using something like airsharing), view, organize, or email them to others. My biggest beef.
I have to echo this sentiment. I want to be able to surf the web and be able to download files from it onto my iPhone. From there, I want to be able to access and use these files and attach them to e-mails and what not.
This is a 3rd party app for this (Folders), but it is very restrictive and you have limited access to the file. So, basically, you can download and view them, but that's it. I want to be able to unzip large files and then use them.
That, and it I can sneak one more in: cut and paste. I have been running into so many situations lately where it would have been of great use.
