The recent “Limera1n surprise” post over at the Dev-Team Blog has been updated to include additional information regarding the Limera1n iOS 4.1 jailbreak, as well as a useful piece of advice for those looking to keep their ability to jailbreak untethered in the future.

An update to the Dev Team’s latest post on iOS 4.1 jailbreaking reveals that “Because the ‘untethered’ part of this jailbreak comes from a userland hack from @comex, you should still backup your SHSH hashes for 4.1.”

Jailbreakers have two methods to do this, either by “letting Cydia keep them, or using Tiny Umbrella.

“This way you can always come back to an untethered, jailbreakable 4.1 on your devices after Apple has closed their 4.1 signing window (they’ll close the 4.1 window once they push out their next firmware version),” the hackers explain.

The infamous team of hackers warns that, “If you fail to do this and ever need to restore to 4.1 again, you can still jailbreak but it will be a tethered JB (you’ll need to connect to your computer to finish the booting process, each and every time).”

“And remember: you can backup your 4.1 SHSH hashes without even being at 4.1 or even being jailbroken, by using Tiny Umbrella,” the team adds.

Softpedia published two jailbreak guides this week for those looking to hack their iPhone, iPod touch, or iPad. As usual, we don’t encourage it (for various reasons), but if you’re going to do it anyway, at least we’re ensuring you’re doing it right.
