I have the same problem as I tried to upgrade my 3g from 3.0 to 4.1. I have read some questions and answeres and tried to use it. The last thing I tried was that I download Sn0wnbreeze 2.02 instead of 2.1. Then it worked. Although it worked for JB and Unlock, it can't pick up the wifi (it's on/off all the time) and no video function at all. Mine right now is 4.1 with baseband 4.26.08. I wanted to ask for help to see I can fix this problem or not
