Back in the good old days of jailbreaking, your first step before upgrading to the latest version of iOS was to plug your device into an app called TinyUmbrella and save your SHSH blobs.

What are blobs? Simply put, saving your blobs gave jailbreakers the possibility of downgrading their devices to a previous version of iOS. Unfortunately, with iOS 5, Apple caught up with the way jailbreakers were using blobs, making TinyUmbrella virtually useless.

Now that’s changed. Three years later, it finally appears that the blobby wind is blowing in the opposite direction, and a new TinyUmbrella beta has been released that once more allows jailbreakers to save their SHSH blobs.

Even if you’re not a jailbreaker, TinyUmbrella is a great little app that allows you to save your iPhone, iPod touch or iPads SHSH blob files locally. What is the actual use of such a technobabble practice? Simple: if you have your blob files stored locally, you can downgrade your iDevice to an earlier version of iOS; useful if your iPhone gets hit with a bug in the latest version of iOS, or an app you can’t live without stops working.

If you are running iOS 5.0.1, you might want to head on by TinyUmbrella’s official website and grab the latest version: it’s been updated to slurp down the latest version’s SHSH blob files.

Upgrading your iPhone, iPad or iPod touch to a new version of iOS isn’t hard, but there’s still a few ways to optimize the process, not just to make the upgrade process as quick and painless as possible, but to make sure you leave all downgrading options available to you in a pinch. Here’s how to do it the right way.

The must have jailbreak utility, TinyUmbrella, a tool written by Semaphore that assists you in saving your iOS devices SHSH Blobs has been updated with new features and a completely redesigned user interface.

You can download the update version 4.1.8 for Mac OS X, Linux, or Windows.

If you are so inclined you can even play around with the core source code of TinyUmbrella.
