Is Zipcar leading a second generation of iPhone Apps?

Fully one quarter of Zipcar members use iPhones, according to Zipcar’ s Luke Schneider, who unveiled a new iPhone app at Apple's Worldwide Developers Conference. Scott Kirsner reports “it got me salivating (I'm a Zipcar member): it offers GPS help finding cars that are available, and can even honk the car's horn to help you locate it in a parking lot. See the video demo here, wherein Schneider shows off their use of Apple’s 3.0 SDK mapkit and demonstrates the Honk icon to spontaneous applause.

From Kirsner’s Innovation Economy blog: “Zipcar CEO Scott Griffith told me today that he has already been testing the beta version on his iPhone, with a few of the company's cars here in Boston. ‘We're finishing the app now, and then we have to do a complete new software download to our whole car network, so that iPhones will have the ability to honk the horn and unlock the car for you,’ Griffith said. The app will be free. Griffith estimates that it'll be available in about four weeks. Future versions of the Zipcar app, he added, might give Zipcar members discounts on music, or deals on iPhone navigation apps or other travel-related apps.

Could this be the start of a new wave, the Second Generation of iPhone Apps? It took fifteen years to get to third generation computers (IBM/360). Can an iPhone generation be less than a year?
