By | December 5th, 2010

A new hack has been released by Sam Bingner (@bingner) which allow you to activate your iPhone 4, 3GS, 3G without the original SIM of the official carrier. The Subscriber Artificial Module (SAM) activates the iPhone for those relying on the ultrasn0w unlock that drastically save battery life.

Earlier, the redsn0w jailbreak used hacktivation procedure to activate your device without the original SIM card. This would enable the phone to operate and unlock, however the iPhone would keep sending the certificates for the original carrier over Wi-Fi or 3G that drastically reduced battery life and eats a lot of bandwidth. This hack would also solve the Push Notifications issue and all the applications including YouTube would work perfectly.

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“.
