Anyway, you can check this blog post to know more and download the stock iOS 4.2.1 IPSW firmware file for your iPhone 3G. After restoring iOS 4.2.1 on iPhone 3G, you can follow this step by step guide on how to update the baseband version of your iPhone 3G to iPad’s 6.15.00 baseband using Redsn0w. You can refer on this tutorial on how update iPhone 3G baseband (05.14.02 to 06.15.00 | 05.16.01 to 06.15.00 | 05.16.02 to 06.15.00). Then refer on this guide on how to unlock iPhone 3G using Ultrasn0w once you have completely jailbroken your device.
