We reported that the Spirit Userland jailbreak for iPhone 3.1.3 OS would be coming Friday, April 30th, the same day the iPad 3G will start shipping, from the creator of the jailbreak, @comex. Unfortunately, @comex just tweeted concerns about releasing Friday after reading an article on Apple patches the iPhone SMS Security home last year saying, “therefore, it is probably better not to release on Friday. (ugh, drama)”
For those of you that are worried about the process of using the jailbreak, the Dev-Team Blog has posted a handy post (below) of what to do and what not to do when using the jailbreak and just some general information you might want to know about Sprit jailbreak. Also some tips on how to back up your SHSH blobs. You may also want to read our “All About iPhone OS 4.0 Jailbreak” post.
Post from the Dev-Team Blog:
Calm before the Spirit storm
At some point after (don’t ask when!) the iPad 3G is actually in customers’ hands, the first “userland” jailbreak since firmware 1.x will be released by @comex. It’s called “Spirit” and was first demonstrated working on an iPad by @MuscleNerd within 24 hours of the iPad’s release on April 3.
Userland jailbreaks are more troublesome for Apple since they expose security weaknesses that exist even for non-jailbroken owners. As such, Apple is likely to close them soon after they’re made public. One recent example of this is the SMS vulnerability exposed at Blackhat last summer. Apple released new firmware to close that hole within a day.
The Spirit jailbreak is most useful for newer devices: iPhone 3GS, iPod Touch 3G, and the iPads. Unfortunately those devices are the same ones that Apple can prevent you from downgrading unless you’ve got a backup of your personalized SHSH blobs. Unless you’ve backed up your SHSH blobs for vulnerable firmware versions, you’ll lose the ability to use the current Spirit jailbreak if you accidentally upgrade.
Please take the steps now to backup your SHSH blobs. Use either Firmware Umbrella to create a local copy, or go through saurik’s server. If you are getting an iPad 3G, it’s safest to backup your blobs using Firmware Umbrella, in case saurik’s server gets bogged down with requests.
Other things about Spirit that are useful to know:
* Spirit is an untethered jailbreak.
* Spirit works on all devices. (However, the redsn0w and PwnageTool flows will continue to work on those devices they’ve always worked on)
* Spirit does not include a carrier unlock. (Please don’t bug @comex about that)
* Spirit requires your device to be activated or hacktivated
Please make sure you have your SHSH blobs backed up! While @comex has indicated he’s not going to release the very minute the iPad 3G is out, there’s no telling what Apple might do anyway.
