his guide is for those who updated their Baseband to 6.15.00 on firmware 4.1 and 4.2.1 for iPhone 3g and 3gs. This is not for iPhone 4. The method is available everywhere but it is very difficult to understand the guide all others have posted.

This guide written by us is for all Noob’s who are trying this for first time and normal users also who were facing problems while doing this. I have tried this on my iPhone and I got succeeded. So if you want to try so try at your own risk and me or the community will not be responsible if you screw your device.
