I live in Mesa, AZ (suburb of Phoenix) and I own a Nexus One with 2-year Tmobile. I have tried using data on my phone all over the Phoenix metro area, and my fastest download/upload speeds, no matter where I am at, are about 70k. I have friends in Phoenix who own android phones with Tmobile, and they have used their phones right in front of me. They get download/upload rates much higher than mine. What steps can I take to make my TMobile 3G data run faster? I have already used the 4636 trick and set the phone to WCDMA only.
