One of the great features of the iPhone's soft keyboard is that it has a nice big .com button that you can press when you're typing in a domain name. But what happens if you need to type a .net or .org domain? Fortunately, there's a shortcut for that.To access a selection of additional domain extensions, all you have to do is tap and hold down the .com softkey. This will bring up a menu that will allow you to select from .net, .edu, .org, and .us. If you're looking up a .xxx domain you'll have to type that one yourself, and you'll still need to add a .au for Australian sites, but otherwise this shortcut should save a few extra taps.
