TinyUmbrella for both Windows and Mac has been updated to version 5.00.07 to support save iOS 4.3.5 SHSH blobs for iPhone, iPod touch and iPad. This will help you to save SHSH certificates for iOS 4.3.5 as well as update iPhone 4 baseband. This is the first time updating iPhone 4 baseband functionality has been enabled in TinyUmbrella.

The iPhone 4 baseband update option should only be used by those who know what they are doing. If you are on a software unlocked iPhone, you should definitely not play with this setting. Anyhow, before you do proceed, take notice of the following:
  1. First, the version you WANT to restore to and the version Apple is currently signing must BOTH have the same baseband. This is important or else the baseband update will not work and you will get a 10xx error and need to use fixrecovery. (Works for iPhone 4 - will not work for iPad 2)
  2. Second, you need to realize that checking the box WILL UPDATE YOUR BASEBAND.
You have to manually select update iPhone 4 baseband option whenever you start TinyUmbrella. It will never be on by default.

As a reminder, to save your SHSH blobs, simply connect your iDevice via USB to your computer, launch TinyUmbrella, and click the “Save SHSH” button.
