Delivery Status is a dashboard widget with a very simple purpose: to help you track packages. You can set up multiple widgets to track multiple packages. It covers just about every shipping service and you can even track orders from companies like Amazon and Apple. Nice, but it gets better.
With version 4.5, the genius(es?) at June Cloud added a sync service. Your package info can be synchronized with their server. Why? Naturally so all your packages can also be tracked on your iPhone or iPod Touch. No manual sync required. It just works. And its awesome.
Did I mention that this is all free?
Why? Who cares. Just get it.
