We previously has discussed scenario to Unlock iPhone 4 and it was analyzed that if iPhone 4 jailbreak is accomplished then there should be not much delay in unlocking iPhone 4 for official carrier customers. The analysis was based upon the fact that baseband firmware in iOS 4 is already exploited which has been proved by ultrasn0w 0.93 release. Ultasn0w 0.93 can unlock iOS 4 on iPhone 3GS and 3G.
There is a surprise by Apple in iPhone 4 for Hackers. According to Modmyi, they have come to know that iPhone Dev Team who actually released ultrasn0w 0.93 unlock has got their hands dirty with iPhone 4. After their iPhone 4 analysis, it turns out that baseband processor and OS has been changed by Apple in iPhone 4.
The DevTeam and others have been checking through the iPhone 4, and have noticed the baseband runs a completely different OS than on previous models. The iPhone 3G and 3G[S] both ran Nucleus OS on the PMB8878 baseband CPU (aka XGold 608), where the iPhone 2G ran the PMB8876 (aka S-Gold 2). iPhone 4 uses the PMB9800, or X-Gold 618 – running a separate OS – ThreadX, an RTOS by ExpressLogic.
These details show that even iPhone 4 jailbreak is successful it may take some time to unlock iPhone 4 as Hackers have to deal with a new baseband processor and OS. Don’t forget that GeoHot may surprise us with limesn0w unlock.

Update: iPhone 4 Unlock is out as ultrasn0w 1.0-1. Free you iPhone 4 from carrier’s dependence.

Dev team can't do it, it would be better if they just admitted it rather than lead us all on. They should return all donations. That was probably the motive for leading people on, to get donations for funding the unlock that they know they cant do.
