Unlock your iPhone 3G/3GS with SAM to fix push notifications and battery drainage

A great news for ultrasn0w unlockers. @sbingner has made a great hacktivation (unlock) tool called Subscriber Artificial Module (SAM) which allows you to legitimately activate your iPhone using iTunes even though you’re unlocked with ultrasn0w. This hack fixes the push notifications and battery drainage issues which means you get the full benefit of push applications, and your battery life increases.

In order to install SAM you will need to have an iPhone 3G or 3GS running iOS 4.1/4.2.1 with baseband 06.15.00. If not then first jailbreak iOS 4.2.1 and upgrade baseband to 06.15.00 (how-to guide posted here) so that you can use ultrasn0w to unlock.

Follow the steps below to install SAM:

  • Run Cydia from your iPhone.
  • Tap the Manage tab and select Sources.
  • Now tap the Edit button at the top and then click Add.
  • Now add this repo http://repo.bingner.com
  • Install SAM and SAMPrefs
  • Now download the latest redsn0w with Deactivate Option (Windows) (Mac)
  • Run the redsn0w.exe and from options select Deactivate (it will remove the normal patches made to lockdownd and let SAM take over).
  • Now Go to Settings > SAM and tap De-Activate iPhone
  • Connect your iPhone to computer and activate it with iTunes. When done a message will appear on your iPhone saying iPhone is activated.
  • Now use ultrasn0w (how-to guide posted here) to unlock your iPhone to be used with any carrier of the world.
  • Enjoy!

Note: If iTunes says invalid SIM, you will need to manually select the appropriate carrier under one of the methods besides “Automatic” and click on a SIMID.

    If I have already upgraded my BB on my 4.1, jailbroken with redsn0w before and installed the SAM modules… I’m confused as to how I use the De-Activate iPhone from redsn0w.

    I tried the deactivate redsn0w with 4.1 IPWS but gets stuck half way while uploading ramdisk to my iphone.

    I tried to deactivate from within SAM of settings and reconnect to itunes… nothing happens? help please.

    I’m confused… My iphone 3gs is already jailbroken with iPad BB and iPhone 4.1.

    Tried the De-Activate redsn0w but during uploading Ramdisk it gets stuck there.

    As well as tried deactivating from SAM and connecting to iTunes but nothing happens. Apps still ask to connect to iTunes for Push Alerts.

    Please help?

    Cool – i tried this, was a pain but worked on my 3G.

    I followed the exact same steps
    using ios 4.2.1 customized with pwnage
    used redsnow to set to DFU and installed the ipsw with iTunes
    Installed SAM first – took a while and a couple of reboots because cydia also installed the necessary updates and upgrades
    Ran redSnow again to deactivate
    Used SAM to deactivate
    Ran ultrasn0w
    …and am in business. Tested the notifications through my own iphone app, worked like a charm. But i think i waited for about half an hour for the changes to take effect.

    Thanks a ton!

  • Veeru

    me again, push notifications worked for a while, but stopped after that. Guess its cause how ios 4.2 checks for the activation or something. Any workaround for this?

  • hobaa

    @veeru maybe its because your certs are out of date im not a pro or an advanced user but have you tried re-doing the process again?

  • tj

    Has anyone had any better luck with this? I want to know before i spend time with it and then having the same issues in an hour like veeru. Is there a better fix or are we all SOL?

  • Pepe

    ok. i got stucked at step 7 (Now Go to Settings > SAM and tap De-Activate iPhone)
    my sam does not have this option. it has a hackivated slider selected and tells me that my iphone is currently factoryActivated.
    i even removed ultrasnow and keeps telling me that.

    am i missing something?

    Thanks for your help

  • eydivad

    Stuck on Activating iPhone via Itunes. It keeps saying I have an unsupported sim… The only way I can connect to Itunes is by hacktivating.
    My carrier is Optus_au 50502 but I don’t have the simcard. Help?
