By | July 18th, 2010



Apple recently released iOS 4.0.1 firmware for iPhone primarily to update the signal calculating formula for the popular smartphone. Fortunately, the iPhone baseband was not updated with this release making it easy to unlock your iPhone. However jailbreak for iOS 4.0.1 is only supported iPhone 3G for now, but we can expect jailbreak and unlock for iPhone 4 and 3GS soon.
