Dropbox is an excellent file-syncing app, and so we’d be remiss if we didn’t include it here. If you want access to your important files on your iPhone, Dropbox can provide. Anything you sync to Dropbox can be temporarily viewed on your iPhone or saved for later viewing. You’re not confined to the Dropbox app either. You can save photos to your library and email a link to any file for sharing with others. There are also many great apps using the Dropbox API, expanding all the things you can do with your Dropbox account on your iPhone. With iOS 4.2 on the horizon, maybe we’ll even get wireless printing support from within Dropbox as well. Regardless of how you use it, it’s a great way to manage your files and always keep them in sync and backed up.
It’s hard to pick when there are so many great apps. While not everything could make the short list, here are some special mentions that are definitely worth a look.
Google Mobile App: If you love Google (but don’t use Android), the official Google Mobile app quickly links you up with all your Google services as well as provides an excellent voice search.
Documents to Go: Pricey, but if you need a mobile office suite for the iPhone, Documents to Go is what you’re looking for.
OmniFocus: OmniFocus is another king of the GTD category that makes a great companion to the desktop app of the same name. The iPhone app syncs to the cloud and makes use of the mobile platform by integrating things like your location.
