Absinthe v2.0.2 Untethered Jailbreak Tool for iOS 5.1.1, Download iOS 5.1.1
According to ih8sn0w official blog post for Sn0wbreeze v2.9.5:
“What is New?
Added 5.1.1/9B208 untether payload for the iPhone 4 GSM.
Added iPhone 3GS (iPad Baseband users) location services fix.
As stated many times in the past, sn0wbreeze cannot be updated to work on A5(X) devices until a low level exploit in DFU or iBoot is found and made public. Therefore, A5(X) users will have to rely on using the lovely absinthe.
A5(X) Baseband Preservation/Hacktivation?
For those running A5(X) devices and need to preserve your baseband, there is nothing you can do at the moment. For those wanting to hacktivate, the only advice I can give is to buy the carrier’s SIM (the one its locked to obviously) on ebay. The SIM does not have to be active with the carrier to activate the phone.”
Sn0wbreeze 2.9.5 is only available for Windows users for untethered iOS 5.1.1 jailbreak over A4 devices, so A5 Devices users can do untethered iOS 5.1.1 jailbreak with Absinthe v2.0.2 which is available for Windows, Mac and Linux users.
