I have iPhone Developer Program.

And My iPod touch has iPhone OS 2.2.1.

I wanna update my touch to 3.0.

But I cannot find the link for getting iPhone OS 3.0

Please let me know how to get iPhone OS开发者_C百科 3.0 and 3.1

In addition to what yogsototh said, you can also launch the Organizer from within Xcode and, with your device plugged in, it should give you a link to the update location.

Just launch iTunes and connect your iPod Touch. When clicking on the iPod touch icon you'll have the possibility to upgrade your OS.
