iPhone/iPod touch: Consider Opera's bluff called. The browser maker's submission of Opera Mini to Apple's App Store has been approved, granting iPhone OS users a browser that uses server-side compression for slow connections, syncs with desktop Opera and offers other perks.
Our sibling site Gizmodo tried out Opera's agility on a weak EDGE connection in New York City, and ruled it "actually kind of great". Opera's Mini browser on iPhones also offers a more true tabbed browsing experience than the built-in Safari, and can sync bookmarks, Speed Dial startup thumbs, and even your current browsing status to desktop browsers and other mobile devices.
If you're frequently fighting a slow connection, or just want to try out something new on your iPhone, give Opera Mini a go. It's a free download for devices running the iPhone OS.
