CutYourSim, a company that makes SIM cutters, is out with a service they claim permanently unlocks your GSM iPhone 4, 3GS and 3G – without the need for jailbreaking. It’s an “official iPhone unlock”, they explain, and will carry on forever. This lets you unlock your device for use with any carrier and update it to the latest iOS firmware and baseband without waiting for an unauthorized unlock to be released:

The unlock will work with any iPhone version, and any baseband version, no need to worry about updating to the latest version anymore.

The iPhone Dev-team seem to be endorsing this solution. It doesn’t come cheap and will set you back $169 per device. Best of all, the company says, the procedure won’t void your warranty. How’s that possible? offers one possible explanation. Read on…


The site speculates that CutYourSim must have found a way to access Apple’s database that holds unique IMEI numbers. It’s highly unlikely they hacked Apple’s own database, but they could have accessed it from a carrier’s online backend, the author explains.

From there, it’s a simple matter of whitelisting your device’s IMEI, which removes the lock on your device. If that’s the case, something tells me Apple will soon ask its carriers to tighten their online security in order to prevent unauthorized IMEI whitelisting. They might also send their legal sharks after CutYourSim.
