Earlier today @sbinger released a cydia tweak SAM (Subscriber Artificial Module) to do official activation of iPhone running on iOS 4.2 and now iPhone Dev Team has updated the Redsn0w jailbreak tool to support this new app.
Redsn0w 0.9.6 b6 brings a new option “Deactivate” for iPhone 3G and iPhone 3GS users. This option will remove the normal patches made by Redsn0w to lockdown and let SAM take over. Read the complete details after the break.
From official iPhone Dev Team’s blog:
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 SAM.
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!
So If you rely on unlock and want to resolve the battery and push applications problem, follow the steps below:
Step 1: Jailbreak and unlock your iPhone 3G, 3GS with Redsn0w 0.9.6 b6 according to the instructions posted here.
Step 2: Install SAM on your jailbroken iPhone as mentioned here to activate your iPhone officially with iTunes.
Step 3: Run the latest Redsn0w 0.9.6 beta 6 and select “Deactivate” option to let SAM take over.
