Two days back Apple team released firmware update 2.2.1 for iPhone and iPod Touch. But Dev Team has strictly warned iPhone 3G users and suggested not to update their iPhones with new firmware. If you update iPhone 3G with 2.2.1 firmware then you won’t be able to unlock it with yellowsnOw.
However, iPhone 2G and iPod Touch users can update their iPhones to firmware version 2.2.1. There is no problem in unlocking these devices with new firmware update. You can use same method that you have used in the past updates to unlock iPhone.
You might need jailbreaking tools to jailbreak your iPhone and iPod Touch. It is recommended to use QuickPWN 2.2.5 or PwnageTool 2.2.5. Currently these tools are available for Mac users only, hence Windows users have to wait.
