—AdMob: It has released a special ad unit designed for the iPhone. AdMob’s new iPhone ad unit for Starbucks includes a Starbucks ad that, when clicked, slides down allowing the user to enter a Zip Code. Doing that opens the iPhone’s Google Maps application which directs the owner to the nearest Starbucks.

—Facebook: A pretty cool mobile version of Facebook, especially adapted for iPhone…uses cues from iPhones UI.

—Meebo: The Web-based chat client has adapted it for iPhone and works well…among the best of iPhone IM apps.

—Then, a contrarian view on all these iPhone-adapted online apps: “The IPhone Is Internet Explorer 4 All Over Again”: “In suggesting that developers use the web to build iPhone applications, what Apple has done (perhaps inadvertently, perhaps not) is force the creation of a subset of the mobile web that only works with the iPhone’s unique features—namely the touch-screen interface…In essence, Apple has forced a third tier of websites on the world by failing to provide developers with an alternative means of creating applications on the iPhone.”
