I opened my electronic mail today on my iPhone four and discovered that iOS 4 now detects various tracking numbers and links them to the acceptable tracking web site. Not a enormous find, but defiantly valuable hidden feature of iOS four. Click on a tracking number in your electronic mail, and Apple will present you with the following display screen. When you click “Track Shipment” iOS 4 will figure out which shipping provider the amount applies to and will hyperlink you to the proper tracking web site.
Have you found any not so effectively recognized functions in iOS four?
