Jailbreak or Unlock iPhone 4/3Gs/3G in a Minute
Written by Editor, Dec 03, 2010
Apple fans have been waiting for a new Jailbreak and a Carrier Unlock for the new iOS 4.2.1, and the iPhone Dev Team has released the goods. It may not be simple, but at least a solution is available. One of the most fortunate thing was that the newer upgrade did not update the baseband, and so the baseband remained at 05.13.04. So jailbreak and unlock iPhone 4, 3G and 3Gs became much more easier, however the good thing is that iPhone 4,3G,3Gs can be unlocked and jailbroken on the iOS 4.0.2/4.1 or 3.1.3 at the moment, because the current jailbreaking & unlocking tools are compatible with iOS 4.0.2/4.1 or 3.1.3. Unlocking Ltd. has introduced a fresh iPhone 4 unlock software that will allow users to explore their Apple iPhone's customization and application capabilities. Specifically, it can "jailbreak and unlock iPhone 4.2.1, 3G 3Gs and iPhone 4 4.2.1."
Now we can jailbreak or unlock iPhone 4/3Gs/3G with the latest tool that allows iOS jailbreak 4.2.1/4.1 and that is compatible with Cydia and MobileSubstrate as easy as ABC. As you've said, this jailbreak is compatible with all models of iPhones but to different degrees. The new tool available at UnlockGuide website is very simple to use and guaranteed to jailbreak and unlock iphone4/3GS/3G running iOS 4.2.1 or older versions.
If you have a newer model (iPhone 3G and new iPhone bootrom 4), your Jailbreak iPhone 4 will be tethered. Indeed, if you have not installed any applications that interfere with the functioning of the SpringBoard or CommCenter, your iPhone will boot up correctly. However, if you have installed applications that require MobileSubstrate (Infiniboard example) and that interfere with the normal operation of SpringBoard, your iPhone will remain stuck on the Apple logo at startup. We also remind those wishing to conserve or unlock iPhone 4, it should not be used redsn0w and update your phone iOS 4.2.1. Make the update via iTunes 4.2.1 iOS 10.1 (this is important) using the firmware you just downloaded.
