I tried install an iPhone OS3.0 to iPodtouch. but I couldn't. 

I used the iTune and Organizer for I install the iPhoneOS3.0. The iTunes say "The iPod"xxxxxx" could not be updated because the firmware file is not compatible". The Orginezer was not selected the iPhoneOS3.0.

Because My acquaintance installed the iPhoneOS3.0, I'll learn about how to install iPhoneOS3.0 by him.



I restarted develop the my application "YubiFude", because I'll attend lab sessions "Quartz 2D Lab" in WWDC2009 . I 'll master understanding and accomplish "YubiFude" before WWDC2009 started.



Today, I started develop "YubiFude" without a Interface Builder. It's do fine. Next, I'll finish the developing before tomorrow.
