Getting jailbreak & unlock tools for every new iPhone firmware release isn’t simple task, however with the brilliant iPhone hacker crews like iPhone Dev team, every firmware has been jailbreaked and unlocked in reasonable time except iPhone OS 3.1.3.
The recently released iOS 4.2.1 is already jailborken with Redsn0w 0.9.6b4 but unlock tools are yet to be released. The issue with Redsn0w is you can’t preserve baseband. Hence many users will be holding back to updating to iOS 4.2.1 until Ultrasn0w unlock tool is released. If you are one of them or accidently updated to iOS 4.2.1 then here is good news for you.
Musclenerd member of iPhone dev team has confirmed the ETA of upcoming Ultrasn0w iOS 4.2.1 baseband 05.14.02 unlock tool for iPhone 3G & iPhone 3GS. As per Musclenerd Tweet,
“Good progress today…everything is on track for updated ultrasn0w by Sunday/Funday at the latest (longer for iPhone4!)”
We should have Ultrasb0w iOS 4.2.1 unlock tool by coming Sunday. Sorry iPhone 4 users you may need to wait little longer.
