Christopher Null - Not thrilled with the iPhone's integrated *** browser — Safari? Check out the new release of Opera Mini for the handset, the first serious browser alternative to become available for the iPhone. (While you'll find other *** browsers listed in the app store, they all use the ***kit rendering engine, which is the basis for Safari. They may look and feel a little different, but ultimately they render *** pages almost identically, so they aren't really worth dealing with.)
