If you search for “browser” in the App Store, you’ll get dozens of applications, each purporting to be an alternative to the iPhone and iPod touch’s built-in Safari browser. In a sense, they are alternatives, since they look different and might have a few unique features. But they’re really all Safari underneath — Apple will only approve browsers that are basically built with Safari guts using a reworked user interface. On the down side, this means we won’t be seeing alternative browsers from the likes of Mozilla or Opera any time soon.
