DO NOT UPGRADE your iPhone 3G to Firmware 2.2.1

WARNING!!!
Apple came out Firmware version 2.2.1 in Feb 2009. There are many people upgraded their iPhone 3G to this version by purposely or mistakenly, and their iPhone can never be unlocked by yellowsn0w 0.98 (still the lastest version as of today 23rd March 2009) which only work for Firmware 2.2 Baseband 2.28.00.
You are able to jailbreak your Firmware 2.2.1 iPhone 3G with QuickPwn 2.2.5-2, but it can not unlock the phone to work for your Mobile Service Provider, since Firmware 2.2.1 will also upgrade your Baseband from 2.28.00 to 2.30.03, which is not support by yellowsn0w yet. You will then have your expensive iPod…
There is another way to make the Firmware 2.2.1 Baseband 2.30.03 iPhone working with your Mobile Service Provider. By using RebelSimcard, or TurboSimcard, or XxxSimcard. But your better check properly on the version that support that. And do put in mind these solution is not a prefect solution. There are a lot of complaints on these solution.
Read it out carefully and decide your move. If you are in this situation.
Thank you for reading this post.
