iOS 4.3 GM has already been released to developers by Apple. This latest firmware update for iPhone 4, iPhone 3GS, iPod Touch 4G, 3G, and iPad whose final version will come out on March 11. TinyUmbrella, the tool that lets you save SHSH blobs for iOS devices is now updated to version 4.21.13 adding support for iOS 4.3 GM.
Description from TinyUmbrella’s blog :
”This update provides iOS 4.3 GM support as well as uses your system proxy settings when launching the TinyUmbrella loader. I’ve also made a few tweaks to streamline the currently saved shshs. I’m still working on the windows recovery kick out fix for 4.2.1 – I should have that finished this week (hopefully). Enjoy”
For those not familiar with TinyUmbrella, it is a utility that allows you to save SHSH blobs, files that are necessary when you try to downgrade your iPhone to a previous iOS version that Apple is no longer signing. Without these SHSH blobs, you can not downgrade the iOS version. While you may not care about it right now, if you plan to jailbreak in the future it is highly recommended you save your iDevice’s SHSH blobs. These SHSH blobs may also come in handy for new jailbreaks, such as Jailbreak Monte.
To save your SHSH blobs, simply download TinyUmbrella, connect your iDevice via USB to your computer, launch TinyUmbrella, and click “Save SHSH” button.
