For a 3Gs which is best? any advise? I am currently pwned on 3.1.2 Are there any advanages for preserveing my old base band (5.11.07)? maybe for future software upgrades? The recently release of ultrasnow unlock over blacksn0w has been working great for me on 3.1.2, with better battery life, no wifi issues, no corrupting baseband files every couples of months. Thanks in advances.
