Today at iPhone 3.0 event, Apple starts off with Scott Forstall, the SVP of iPhone software, with details on the iPhone 3.0 OS and developer programs. First in line is the additional of  a paid app -- In-App Purchase – that will prompt you from within the software to buy an update such as a city guide where you can add individual cities, while the freebie version will not attempt to remind you for an update or ask to purchase additonal add-on in that app.

Next up is peer to peer connectivity with new APIs include tools to bring up nearby iPhones or iPod touches that would automatically identify running apps and create an instant IP connection with existing Bonjour technology, wireless over Bluetooth.  A technology suitable for game apps but Apple says it works for any peer to peer app with quick fire connection without the need of Bluetooth pairing or typing in a password.
