Apple Iphone OS 3.0.

Yes, I have downloaded the OS 3.0 and installed it onto my Iphone 3G. It worked like a charm. It is good and the menu is so much faster as compared to the old 2.2.1. I've heard that UltraSnow is going to be released on 17th June 2009. That is to facilitate customers to unlock and jailbreak their Iphones. A word of caution...By unlocking/jailbreaking your Iphone, you will lose your Iphone warranty...
