One of the few things we put too much emphasizes is to save your SHSH blobs of any firmware you upgrade to. For jailbreakers, its one of the most important things. Why ? Because it helps you to downgrade your firmware to an earlier jailbreak able version.
We want our visitors to be on the same page with us. TinyUmbrella has been updated to version 5.11.00 and now it allows you to save SHSH blobs of iOS 5.1.1. So those of you who have their devices currently on the iOS 5.1.1 are advised to save their SHSH blobs.
Some of you must be thinking that iOS 5.1.1 does not have untethered jailbreak so why saving its SHSH blobs. Well, yesterday we have updated that Pod2g’s exploit for upcoming untethered jailbreak works both on iOS 5.1 and iOS 5.1.1. So its better for you to take actions now.
So if Apple releases iOS 5.1.2 or iOS 5.3 to fix the upcoming jailbreak, you can always come back to iOS 5.1.1 by downgrading it.
