Gizmodo confirms what we feared during our meta-live-blog -- the bits that receive the information from the shoe-insert are built-into the 2nd Generation iPod Touch and not any other Apple device. That's not surprising -- hardware is as hardware does.
That's not the real bad news, though. The real bad news is that the 'dongle' that iPod users have been able to use for those transmissions in the past continues to be incompatible with the iPhone and the 1st Gen iPod Touch and that's not a situation that's likely to change.
So if you're looking to track your run without buying new gear, it looks like you'll be doing it the old fashioned way.
