While browsing, just saw this tutorial to unlock iphone 4.
Can anyone verify if the steps or the tutorial is fine and will jailbreak and unlock my phone.

iPhone 4: 4.2.1 iOS Update, Jailbreak, Unlock without BaseBand upgrade

Thanks

What is the "version" and "modem firmware" of your iPhone 4? Both can be found in settings>general>about

version: 4.1
firmware: 02.10.04

Im sorry but since the "modem firmware"(baseband) is currently not able to be unlocked. The guide will work just fine though and it will update your iphone to 4.2.1 and keep the baseband at 2.10.04 but as I said previous 2.10.04 is locked. Step 7 will jailbreak your phone.
