Sorry, no they haven't. The touch 4G is an A4 based device, the same as iPhone4. If you have shsh blobs it can be downgraded. As I said, we have lots of stickes that explain the how and why. Whilst it sucks your boyfriend could not downgrade his because he did not save blobs when they were available, it does not make it true for all iPod Touch devices.Originally Posted by Charlamayne
The facts are that only the iPad2 3G model and iPhone4S are impossible to downgrade as things stand today. All other devices from the iPhone 3GS to iPad2 Wifi can be downgraded IF the owner saved blobs for the firmware version they want to be able to restore to. Unfortunately you cant do that retrospectively once you've moved to 5.0.
