T-Mobile G1 walkthrough videos: maps, browser, Facebook etc

More demo videos of the T-Mobile G1 released. T-Mobile CEO said they will unlock these phones for you 90 days after activation, and will let you tether your phone to a computer as long as its not a major network issue. Another thing is, when you sign the contract, you will be limited to 1gb of data per month before they throttle your d/l spee to 50kbs….not to happy about that…
