Dropbox Brings Cloud Storage Within iPhone's Reach.Still, we know a lot of Gadget Lab readers are Dropbox users, so enjoy the new interface and the new "Open In" command, and join us in quietly grumbling that Apple really messed up file-organization on the iPad. There are also hacks to let you email your files into Dropbox, but this still creates the problem of duplicate files, essentially a new version of your file every time you save. This is a limit of the other apps, but we can foresee a third-party text-editor, say, that would offer to send the file to Dropbox.
The problem is that you can't yet save anything back into Dropbox.
Tap the "Open In" icon and choose from the list of available apps. Pick a file: a photo, text document, PDF, spreadsheet or anything supported on the iPad.
