If you're like me, your among the millions of people that ordered an iPad 2 on March 11 and is still waiting for it to arrive. If you're obsessive and/or have a compulsive need to follow you iPad's progress through the supply chain, I recommend that you download Junecloud's Delivery Status Touch for iPhone ($4.99) from the App Store).
One of the main problems with my iPad 2 order was that it sat in Apple's queue in Shenzhen forever without being assigned a tracking number, requiring a trip to the apple.com/orderstatus page -- or so I thought.
Once your package is actually "on the truck" Delivery Status can track its progress through all the major international carriers including USPS, UPS, FedEx, DHL and many others.
A truly OCD feature is being able to see your package’s location in Google Maps, but it doesn't end there. Version 4.3.1 features a redesigned, Dashboard widget and web portal that keeps your tracking numbers in sync across all platforms. Scary good app and well worth the $5.
