what ios builds does apple still sign becasue i am about to attempt ios5 hacktivation and in the event i have to go back what does apple still sign? ( i heard it was 4.2.1 or 4.3.5 something like that i forget.)
well, technically they still sign the 4.2.1 firmware because that is the 2nd gens' highest possible firmware that they can go to, but if you havent saved your shsh blobs for your phone for 4.2.1, then im not sure that you can actually use these
iPhone 2g and iPod Touch 1G - 3.1.3 iPod Touch 2G and iPhone 3G - 4.2.1 and 3.1.3 3rd Gen+ devices - Always the latest firmware ATM 5.0.1.
