iPhone OS 4: File transfer via iTunes sync

Again it looks like the iPhone is finally getting in iPhone OS 4 what the iPad got in 3.2 with the file/document transfer feature now exposed in iTunes sync.

While the iPad version identifies document-friendly apps (like Apple’s own Keynote, Numbers, and Pages) and lets you find and sync over files, the iPhone OS 4 beta 3 version currently only shows Mail and doesn’t really let you do much. However, it stands to reason this will at least reach feature parity with the iPad when Apple releases iPhone OS 4 to the public later this summer.

Now all we need is an elegant way to share and wirelessly sync those documents across multiple devices and users. MobileMe 2.0, souped up iWork.com 2.0, where are you?
