Apple just released 5.1.1 with minor bug fixes and improvements while taking HDR photos.Developer of TinyUmbrella, NotCom has recently tweeted he has updated TinyUmbrella to version 5.11.00b to support saving iOS 5.1.1 SHSH blobs.
If you updated your iOS device to the iOS 5.1.1 firmware then you will indeed want to take advantage of TinyUmbrella 5.11.00b and save your SHSH blobs while you still can. The importance of having saved SHSH blobs can be seen with the recent downgrading solution released by the iPhone Dev-Team that allowed A5 iOS devices to be downgraded from iOS 5.1.1/5.1 to iOS 5.0.1 for anUntethered Jailbreak. The only requirement for this downgrading solution was saved SHSH iOS 5.0.1 blobs, something that not everyone had done. So, the bottom line is make sure you save your SHSH blobs for each iOS version you update to.
