Yes you read it right! Carrier unlock for Baseband 05.14.02 on iPhone 3GS, 3G iOS 4.1 seems to be almost ready. MuscleNerd of iPhone Dev Team has confirmed that ultrasn0w software unlock for iPhone 3GS and iPhone 3G on iOS 4.1 and iOS 4.2 running 05.14.02 baseband will be released in a day or two at most, once iOS 4.2 is released to public.

simplysaru: @MuscleNerd thanks.. how long would the wait be for 4.2 any approximate time
MuscleNerd: @simplysaru if you’re on 3G or 3GS, just a day or 2 at most after 4.2 is public (just enough time to verify stuff)
However, you can still carrier unlock your iPhone 4 on iOS 4.1. If you have the iPhone 4 on iOS 4.1 then you are out of luck as you are already on baseband 02.10.04. If not, then follow the complete guide on how to upgrade iPhone 4 to 4.1 firmware without upgrading its baseband and later unlock it using ultrasn0w or alternatively, you can jailbreak your iPhone 4 4.1 by installing custom firmware using PwnageTool and later unlocking it using Ultrasn0w.
