Apple has released the expected new iOS 4.1 beta firmware for developers and to our joy Redsnow 0.9.5 beta 5 can be used to jailbreak this new version on iPhone 3G and iPod Touch 2G (non-MC). iOS 4.1 beta includes change to the formula for calculating the signal strength bar, besides other changes, but it might not resolve the reception/antenna issues completely.
How to Jailbreak iOS 4.1:
The all other steps of jailbreaking are same for iOS 4.1 as mentioned in our previous post except a little change.
If you’ve updated to 4.1beta1 on iPhone3G or iPod2G(non-MC), you can use this redsn0w to jailbreak. Just point it at the 4.0 IPSW (the public one, not the developer GM one). (Yes – point it at the 4.0 IPSW even though you’re at 4.1beta1).
