Jailbreak iOS 4 on iPhone 3GS

iPhone Dev Team has just reported that with iOS 4 or higher, Apple has started putting ‘soft’ SHSH blob checks in the firmware.

This means that like iPhone 4 and iPhone 3GS, if iTunes can’t get the SHSH blobs for iPhone 3G or iPod Touch 2nd generation (due to signing window being closed), the iTunes restore will error out.

According to Dev Team, soft SHSH blob check can be easily bypassed by using Redsn0w and PwnageTool.
