Saving SHSH blobs is really very important whenever you upgrade to a new firmware. By saving the older versions SHSH blobs, you always have a choice of going back to the older firmware in case the new firmware’s don’t work good on your jailbroken iOS device.
Recently after Apple released iOS 4.3.3 to fix the location tracking issue,the iPhone dev team also pushed out the latest versions of PwnageTool, RedsnOw and others for successfully jailbreaking devices running on iOS 4.3.3. Even the Verizon iPhone 4 got a firmware update to 4.2.8, and softwares were updated to jailbreak that too.
Since there was no way you could save the SHSH blobs for iOS 4.3.3, many people had refrained themselves from jailbreaking their iPhones, iPod Touches and iPad. Well, all those guys can now put on their jailbreaking hats because the latest version of TinyUmbrella has been updated to support saving iOS 4.3.3 and iOS 4.2.8 SHSH blobs.
You can now use TinyUmbrella 4.33 to save your SHSH blobs if you’ve recently updated to the latest version of iOS 4.3.3 or iOS 4.2.8(CDMA).
