About a week prior to getting my iPhone 4, the 3G stopped working on my 3GS.

Basically, I am on a family talk plan, and even though my account was not eligible for a full upgrade. I was able to use another account and then when I picked my phone up they would just make the switch, allowing me to keep my number - etc.

When I went in to pick my phone up, the girl told me that it should all fix itself after we activated my new phone. For the most part of the day my 3G worked fine. I came home and switched over to wifi for the remainder of the day. Today, I was out getting the car inspected and tried to use my phone. Again, the 3G didn't work.

I went back to the AT&T store - they replaced my sim card and it still does not work. The girl told me that they would be putting in a "trouble ticket" and would let me know.

I'm just wondering if anyone else is having issues w/ the 3G?

Here's my YouTube video I made showing what is happening:
