Apple Softens Stance on iPhone Coders (PC Magazine)
iPhone native application developers, take heart: Apple doesn't hate you. And now you have a whole new device to play with.
A couple of PC Magazine folks met with Apple marketing honcho Greg Joswiak yesterday to talk about the new iPods, and thrillingly, he had some answers to interesting questions.

My interpretation: They're the same platform the way a Mac Mini and Power Mac are the same platform. What Greg didn't say, but I surmise, is that means apps for the iPhone will likely work on the iPod Touch.
The iPod Touch does not have Bluetooth. Any images on the Internet that may have implied that it did were errors, Joswiak said. Also, there are no games coming for the iPod Touch right now. Read the rest of this post at Gearlog : "Apple Softens Stance on iPhone Coders"
