AHow to unlock your iPhone version 1.1.2

After we tried to upgrade the iPhone to the latest firmware 1.1.2, here is some additional information that you should know for your unlocked iPhone.

1. anySIM unlocked iPhone 1.1.1 may not be bricked after the upgrade.

2. You can still go back to iPhone 1.0.2 from 1.1.2. But you need to go from 1.1.2 > 1.1.1 > 1.0.2. After all, use some techique to reflash the baseband to 1.0.2’s 03.14.08_G. Virgin iPhone 1.1.2 is possible. Take a look of the downgrade steps we did here. You will get the phone function work again using this method.

3. anySIM 1.2 from elite team can unlock the iPhone 1.1.2 baseband 04.02.13_G. But since no luck to jailbreak and activate successfully by using this method, you will get no luck to unlock iPhone 1.1.2 currently.As you can see, we also tried to go from iPhone 1.0.2 (baseband 04.02.13_G) to 1.1.1(baseband 04.02.13_G), but we can’t pass through 1.1.1 and cannot go to 1.1.2. We also find out the anySIM 1.2 hangs sometimes during the unlock, which is scary. Hence, don’t upgrade your iPhone now.

4. anySIM 1.2 is verified to work under iPhone 1.0.2 with baseband 04.02.13_G. It won’t unlock for iPhone 1.1.1 with baseband 04.02.13_G during our test. It also won’t work for UK iPhone.

5. Don’t pay for the UK unlock available here. It is not tested and will be very dangerous. Since secpack is grabbed by iPhone dev team, free unlock will be there very soon.
