Even though iPhone 4 is running iOS 4.0 but the baseband is different from what iPhone 3G/3GS gets when you update to iOS 4.0 and with the news of iOS 4.0.1 on its way to fix iPhone 4 reception issue, situation looks quite complicated for unlockers as Apple may fix existing holes used to jailbreak & unlock iOS 4.0.
