Why are we talking about unlock for iPhone 4 CDMA and 4S models only? The answer is simple. Only these two smartphone models by Apple have 3.0.04 baseband. You know that the iOS upgrade also changes the baseband of the handset, don’t you? Actually, users can always find out what baseband they will get after upgrade beforehand. This information isn’t secret and you can find iOS 6 baseband list online.

There are a couple of ways how you can try to unlock 3.0.04 baseband for iOS 6 iPhone models 4G and 4 CDMA. One of them is R-Sim or Gevey Sim unlock. Have you thought about it? Well, if you have stop thinking about it because this method doesn’t support this firmware version.
