Soon after the release of GreenPois0n RC5.4 Untethered Jailbreak Tool by Chronic Dev Team, Apple was asking users with Unlocked iPhone 4 to upgrade to iOS 4.2.1 to protect their devices from being locked. But no need to worry folks as moments ago Notcom has released TinyUmbrella 4.21.12 with recovery boot loop fixes, which was a major bug in the previous release. It is currently with beta support for iPhone, iPad and iPod Touch. For those of you who don’t know what is Tiny Umbrella, it is a tool which is used to save you SHSH Blobs regardless of jailbreak and helps you in getting out of rec0very mode.
Right now it is only available for download for OS X users but Notcom, the developer of TinyUmbrella has said that he is currently working on the Windows version and will be available for download in a day or two.
