T-Mobile has released another commercial in its myTouch4G/4G-network campaign, this time knocking video calling over wifi. This commercial highlights the limitations imposed by wifi only video chat when one of the users steps outside the wifi zone, or in the case of this commercial, outside the cones. The “glitchy” effect given to the “iPhone4” showcases the need to stay within the wifi range in order to have a call that that doesn’t end up looking like the one above. Glad to see T-Mobile releasing a steady stream of these commercials with AT&T as the intended target, but I think it might be time to turn their sights on the real competitor in the field, Verizon since Sprint can’t even define what 4G is these days.
