iPhone Unlocking

Now jailbroken iPhones can be unlocked for use on other carriers using the SAM (Subscriber Artificial Module) package. The process works with the GSM iPhone 4 and 4S running iOS 5 and equipped with any baseband. This means that users looking to unlock their devices for use on a different carrier don't have to wait until they're out of contract.

The unlock comes thanks to Chinese iPhone developer Loktar_Sun. The SAM package can be installed by first adding the source repo.bingner.com to Cydia on a jailbroken iPhone. For instructions on how to add a repository to Cydia click here.

In case you haven't heard, AT&T started officially unlocking out-of-contract iPhones for customers in good standing earlier this month. The only problem is that AT&T recommends a full restore at the end of the unlocking process, which will wipe an existing iPhone jailbreak.

Luckily you can still unlock your iPhone through official channels without losing your jailbreak by following a few extra steps. When your contract with AT&T ends and you're ready to unlock your iPhone for use with other carriers, first follow the steps at this link to contact AT&T and determine your eligibility.

A few hardware unlock solutions for the iPhone 4S have appeared this month, but Gevey has released a Verizon and Sprint unlocking solution. The Gevey Ultra S claims to unlock both GSM and CDMA, unlike the R-SIM and TP-SIM which do not work with Sprint models.

The new SIM interposer requires that your iPhone be jailbroken, not be running iOS 5.1 or higher and is on one of the following basebands: 1.0.11, 1.0.13, 1.0.14. This is also the only known solution for Sprint handsets. The Gevey Ultra S is $60 and will be available at the end of this month.

Looking to unlock your iPhone 4S for use on other carriers? Now that unlocking fans are still waiting for a jailbreak software solution, familiar unlocking service CutYourSim has reappeared on the scene. In case you don't remember, CutYourSim had a brief business remotely unlocking iPhones for a price.

The company ended up refunding money and closed up shop after their "supplier" couldn't meet demand for its services. CutYourSim is now offering a permanent unlock solution within 15-20 days for AT&T customers for a cool $200.

Another hardware unlock solution has appeared, the R-SIM from Each Supplier. This SIM interposer works with the iPhone 4S running iOS 5 or iOS 5.0.1 making it possible to use the device on any compatible GSM carrier network.

iPhone Dev-Team has not made recent announcements regarding updates to ultrasn0w, the software unlock solution for jailbreakers. One advantage of the R-SIM is that the product does not require a jailbroken iPhone to unlock the device.
