CNET reports that Opera has now submitted its Opera Mini web browser for the iPhone to Apple for App Store approval. First previewed at the Mobile World Congress, Opera Mini is designed to be used as an alternative to the iPhone’s built in Safari browser and promises faster page loading due to server-side optimization and a tabbed browser interface. CNET indicates that Opera Mini 5 running on the iPhone looks and behaves “almost identically” to the version of Opera Mini 5 on other mobile devices but also includes the ability to reload the previous session to maintain a persistent state when relaunched. Unlike other alternative browsers currently available on the App Store, Opera Mini is not based on WebKit, and there has been much speculation as to whether Apple will approve it. Third-party browsers have previously fallen afoul of Apple’s restriction on third-party applications executing code, however in discussing the matter with CNET, Opera CEO Jon von Tetzchner indicated that he doesn’t feel that Opera Mini directly violates anything in Apple’s SDK license as it merely displays web pages rendered on Opera’s own proxy servers.
