AT&T store display iPhone 4 still on 4.0. We jailbreaked its ass, and saved the blobs for a lucky mofo. We’re not going to tell you where’s that AT&T store. Whoever is going to get that iPhone… you’re welcome!
brief explanation of SHSH blobs, and how to restore your iPhone/iPod Touch/iPad once you have them on file…
There’s a lot of confusion about the SHSH blobs, and once saved ( see tutorial here and here ), how can we use them to downgrade our iOS devices. The problem is, that iOS devices have to communicate with Apple’s servers before allowing the installation of any version of firmware (restore or update ) .With the release of Firmware 3.1.3, Apple’s server has stopped certifying all previous firmware and this makes it impossible to restore your device to a previous release. The certification is done through 3 files called IBSS, IBEC and ECID that, once signed, they are a kind of “green light” to install the firmware through iTunes.
