By using the exploit used in latest Absinthe for untethered iOS 5.1.1 jailbreak, iH8sn0w has also released Sn0wbreeze v2.9.5 capable of iOS 5.1.1 untethered jailbreak over iPhone 4, 3GS, iPad 2, 1 and iPod Touch 4G, 3G.
Official words about Sn0wbreeze 2.9.5:
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.
