iOS 4.1 unlock status

iOS 4.2.1 firmware was released on Monday ( Nov. 22nd ) ... resist the urge to update to that version.

There currently is not an unlock for iOS 4.1 and the new 4.2.1. However, an unlock for the 3G and 3GS iPhones is expected within days with one for the iPhone 4s to come a bit later ( not ETA has been given ).

However, one thing that all of you MUST do immediately in order to ensure that you can have a "good" jailbreak for 4.2.1 is to backup what is called your SHSH information. This is information that Apple uses to determine if your device can be downgraded. Typically, Apple does not allow 3GS and iPhone 4 phones to be downgraded, they must stay on the most current version available ( the 3G iPhones do not have this issue and can be downgraded to any firmware version ). However, with saved SHSH information your 3GS and iPhone 4 can be downgraded.

The word from the jailbreak hackers is that your SHSH info for firmware 4.1 must be saved in order to ensure a "good" jailbreak, as I mention above. The process is simple :

1 - Go to the following website and download TinyUmbrella ( at the far right of the page ) for your Windows or Mac system

2 - Plug your iPhone into your computer and run TinyUmbrella ( you may get some firewall messages in a pop-up. Click on Private and Public networks, then "Allow access" ).

3 - When TinyUmbrella loads, click on your iPhone in the left pane, under "Connected Devices" and then click on "Save SHSH" at the top right of the right pane.

4 - In the "Saved SHSHs for " you should see the firmware versions for which SHSH info has been saved : e.g. iPhone4 4.2.1 (8C148) <- this is SHSH information for 4.2.1 firmware for an iPhone 4 As long as you have an entry for 4.1 ( e.g. iPhone4 4.1 (8B117) ) you have done what is requested by the iPhone hackers and are good for a soon-to-be-released jailbreak for 4.2.1 - note that you can stay on firmware version 4.1 for an unlock ... just DO NOT update your firmware right now.


That's it for now.
