Verizon Wireless customers will soon regain the ability to stream mobile video at the highest resolution, but it's going to cost extra. Starting November 3, Verizon Wireless customers will have the option of paying another $10 a month to remove the cap on video resolution.

This is the latest in a series of changes at Verizon related to unlimited data plans and video quality. In February, Verizon offered unlimited data plans for the first time in years, boasting that it would not impose limits on video quality (unlike some other carriers).
