[COLOR=DarkOrange]Apple sneaked in a worthless firmware update (2.2.1) to thwart the attempts of Dev Team to unlock the iPhone 3G via software means. Please stay away from the update till a patched firmware without the baseband update is released. I repeat, baseband cannot be downgraded and since Apple patched the baseband exploit, 2.30.03 which comes as a surprise with 2.2.1 is not unlockable by any means at this time. Save yourself some headaches and enjoy your iPhone as you are till yesterday! Any prompt for updates should be ignored.

iPhone firmware update 2.2.1 improves the stability of MobileSafari. The firmware also fixes an issue where images saved from Mail.app sometimes display improperly in the camera roll. We can definitely live without these updates but yeah, a patched firmware is the key to all the yellowsn0w hopefuls![/COLOR]2) Make sure you have jailbroken your iPhone 3G Firmware below 2.2.1 using QuickPWN 2.2.5

3) Now,if you have access to a Mac, feel free to download PwnageTool_2.2.5 and build a custom firmware. Windows users might want to DOWNLOAD THE COSTUME FIRMWARE and restore to that firmware using iTunes (Hold Shift key (Windows) / Opt key (Mac) while hitting the restore button in iTunes).

3) WiFi Network recommended. (If you don’t have a Wireless Router, try creating an Ad-Hoc WiFi network on your PC/Mac.
