Let me clear this upfront. The following instructions will only help downgrade iPhone 3G which is currently on iPhone OS 3.1.3 with 05.12.01 baseband and older bootloader 05.08
Step 1: To downgrade your baseband from 05.12.01 to 04.26.08, you must first jailbreak your iPhone 3G running firmware 3.1.3 by using any of one these links : http://bit.ly/cbT9vr
Step 2: After you have jailbroken your iPhone, Go to Cydia on your iPhone and Search for Fuzzyband and then install this application.
Step 3: Start Fuzzyband app and touch on Downgrade button to downgrade your Baseband from 05.12.01 to 04.26.08.
NOTE: For those of you who dont know your bootloader, simply run Fuzzyband and it will report the version number for you.
