With the release of iOS 4.3.2 for iPhone 4, iPHone 3GS, iPad 1, iPad 2, iPhone Touch 3G, iPod Touch 4G and iOS 4.2.7 for CDMA Verizon iPhone 4, It is highly recommended to save SHSH blobs of iOS 4.3.1 before you upgrade to iSO 4.3.2. Notcom has already updated his Tiny Umbrella tool. It supports the latest iOS 4.3.1 firmware. TinyUmbrella 4.30.05 allows you to save SHSH blobs of iOS 4.3.1.
For those who don’t know, SHSH Blob is a signature verification file against Apple Server. It verifies that the iDevice is running the latest version of iOS. Saving SHSH blobs will allow you to restore to previous version. While doing so Apple will stop you doing the restore process. To make this happen you have send a request to different servers which forwards SHSH blobs to iTunes by just showing it that its a new version of iOS. This is how TinyUmbrella or iSHSHIT works to help you save SHSH blobs.
