Just shot this video...
Take a look at what happens while running the Speedtest.net app on the new iPhone 4 and touching the bottom left corner where the seam is located.
You can clearly see the effect it has on both download and upload but it is really clear on the upload part of the test. It does this every time and consistently.
The speed actually starts to drop when you touch the side or pauses and then resumes climbing when you lift your finger.
