Yesterday, Apple released firmware 3.1.2. Yes, I know this happened yesterday, but we are currently on vacation in the beautiful countryside of Wisconsin and our AT&T Cellular Data Card is having sketchy service (go figure). :)
According to the Dev Team, you will want to hold off on up upgrading because neither PwnageTool or redsn0w work on 3.1.2. Below is what they had to say on their blog.
WARNING! At 10.20AM PDT on October 8th 2009 Apple released the 3.1.2 version (7D11) of the iPhoneOS.
If you care about your jailbreak and unlock, don’t update your device – 3G and 3G(S) owners should pay particular attention to this warning.
PwnageTool and redsn0w are not yet compatible with 3.1.2
There is no estimated release time for compatible tools (please don’t bug us about this).
Any information we have regarding this update will be posted here.
