If you have an iPhone, you're probably already syncing your e-mails, contacts and calendar, but what about other files? Thanks to the Soonr app, released today in the App Store, you can now sync everything from Excel documents to text documents to pictures. Soonr supports 30 file types and allows you 500MB of storage in a "personal cloud" that automatically grabs the latest versions of your files without requiring you to upload files every time. In addition, Soonr lets you preview files and even print to remote printers. Best of all, it's free to all iPhone/iTouch owners.
