A new unlock method has been discovered that works on every iPhone 3GS, iPhone 4 and the iPhone 4S running iOS 5, iOS 5.0.1 and even iOS 5.1 with any baseband. All you need is a jailbroken iPhone.
Here is a step by step guide:
- Assuming your iPhone is jailbroken and ready to go…
- Open Cydia and add the repo “repo.bingner.com” and then search for “SAM” by sbingner and install it
- Tap on the orange SAMPrefs icon that looks like a SIM card to launch the app
- Tap “Utilities” and select “De-Activate iPhone”, tap “OK” when the deactivation notification pops up
- Now tap “Method” and tap on “By Country and Carrier”
- Tap “Country” and select the country the iPhone is locked to
- Tap “Carrier” and choose the origin carrier the iPhone is locked to
- Tap “More Information” and tap the IMSI number found under “SAM Details”
- Tap on “Spoof Real SIM to SAM”
- Tap back to the primary SAM setting screen, and paste the IMSI number into IMSI
- Connect the iPhone to the computer and launch iTunes, letting iTunes reactive the iPhone
- Disconnect the iPhone from the computer and quit iTunes, then tap on “SAMPrefs” again and flip the “Enabled” switch so that SAM is disabled
- Relaunch iTunes and connect the iPhone to the computer yet again, ignore the “failed to activate” message and quit and relaunch iTunes again
- Wait a minute or two and the iPhone should get a signal from the new carrier, it’s now unlocked and activated
The downside to the SAM unlock method is that it requires a jailbreak, that means if you lose your jailbreak you lose the unlock. If you don’t want to jailbreak or you can’t for some reason, you can officially unlock an iPhone by calling up your carrier and asking them to do so.
This method is found by Lokhtar_Sun and is being said that Apple is very likely to fix this soon, so if you are depending on an unlock… go ahead and complete all the steps in the tutorial.
Let me know what do you think about SAM unlock.
