Hey Everyone, Ever since upgrading to 3.12 (JB) my battery life is beyond terrible. Others have mentioned that it is possible to downgrade to 3.1, which I plan to do today, but is there anything special I need to know about how to do this? Is there an older version of Pwnage tool I should use, or can I use redsn0w? What's the best way to go about doing this. Thanks in advance!
