Apple still signs the IOS 4.1 for some devices

This is great news for those who have an iPhone (or iPod Touch) into a version that you can not jailbreak (like IOS 4.3.5) and want to downgrade but do not have SHSH saved.

Apple is signing yet IOS 4.1 for devices with less than A4 processor, ie all 4 prior to iPhone, iPod Touch 4G, iPhone and iPhone 2.

So if you want a jailbreak untethered iOS to downgrade to 4.1 (you can use any of the tutorials you find on our site), remember to save your SHSH to continue to downgrade Apple once stop sign.

Note: To save SHSH not need to be jailbroken.
