iPhone Dev-Team has just released redsn0w 0.9.6b6 (Windows and Mac) to jailbreak iOS 4.2.1 on iPhone 3GS/3G and update their basebands to iPad baseband 6.15.00, as most of you know that redsn0w 0.9.6b5 did that, but the new version of redsn0w 0.9.6b6 brings hactivation and increases battery life substantially, as we reported earlier, it was the most prevalent problem after unlocking iPhone 3GS/3G with ultrasn0w 1.2
Developer @sbingner (author of TetherMe) has made some excellent progress devising a new hactivation method that kills two birds with one stone for all you ultrasn0w unlockers. His tool, “Subscriber Artificial Module (SAM)” tricks your iPhone and iTunes into creating legitimate activation tickets even though you’re unlocked with ultrasn0w. This means you get the full benefit of push applications, and your battery life increases substantially. If you’d like to try it out, check out http://www.bingner.com/SAM.html
To help make it easier to try out @sbingner’s tool, we’ve updated redsn0w to include a new “Deactivate” option for the 3G and 3GS. Use this option *after*
you’ve installed SAM…it will remove the normal patches made to lockdownd and let SAM take over. (sbingner plans on making a button to do this within SAMPrefs too). Great work, @sbingner!
