How can I unlock my iPhone 3G on 4.1?
If you want to unlock the iPhone 3G with 4.1 installed, you are going to need to use something like Ultrasn0w. Just make sure you have 4.1 already installed on your iPhone, and you also want to make sure that your iPhone is jailbroken. You can follow these simple steps in order to unlock it: http://www.softsailor.com/how-to/42662-how-to-unlock-iphone-3g-on-ios-4-1-using-ultrasn0w.html.
If your modem firmware is 05.14 it cannot be unlocked at this time it can only be Jailbroken.
