if your using a 3g iphone right now you cant as far as I know the baseband is different. 2g iPhone is the same baseband still.

WTF ?? This video is full of it. It's a 2G not 3G. Show me the Baseband version ... not the iphone fw.
BTW, this post is in the 3G section !!!!

I was think the same thing but in the video you see the 3G icon next to the signal etc.

But like you I have serious doubts about this video being a real 3G iphone
