Hello guys! A college senior came over to me asking if I could see why his recently acquired iPhone 3G (used) was not getting any cell reception. He told the iPhone was jailbroken and unlocked. I checked the phone. I saw that the OS version was 3.1.3 but baseband was the dreadful 05.14.02. At first I wondered how an iPhone with an older iOS had a newer baseband. Then I realized -- the previous owner probably updated the iPhone to 4.x and downgraded the OS to 3.1.3. Sadly, the baseband got stuck at that notorious version. I then checked the Internet. The baseband is still not unlockable, but it can be overwritten with iPad baseband which can be unlocked! However, after that, it is said that no official Apple firmware can be applied. So I want to ask -- Should I upgrade it to the iPad baseband? 1. Are there any issues with using iPad BB on the iPhone 3G? 2. Should I instead wait for an official unlock for 05.14.02?
