Jailbreak utility TinyUmbrella got a big update today. Version 4.1.9 is now available for Mac OS X, Linux and Windows. TinyUmbrella is a staple tool in the Jailbreak community. With the ability to save SHSH blobs, TinyUmbrella allows jailbreakers the ability to downgrade to a previous iOS version if necessary. This can be useful when users want to jailbreak their iOS devices, but have upgraded their software to an unsupported version. Users must save their SHSH blobs before upgrading to the latest iOS version, if they want to be able to downgrade later.
Currently, users looking to unlock their iPhones cannot use TinyUmbrella to do this. According to the TinyUmbrella blog:
“DO NOT USE TINYUMBRELLA in an attempt to save your baseband. It will not work. The baseband protection is for iPhone 4 *ONLY*.”
TinyUmbrella now has a totally redesigned interface for all operating systems...
