A Turkish company claims to have successfully unlocked an iPhone 3G equipped with v3.1.3 firmware as well as modern baseband code. Recent changes to Apple software updates have put a chill on the unlocking scene, as updating to v3.1.3 simultaneously installs the v05.12.01 baseband, which can not only block new unlocks but also wreck previously established ones. Hackers must normally avoid installing the modern baseband to preserve earlier unlocks.
