Qik by now, right? It's most closely linked to Sprint's EVO 4G, but it looks as if the video calling service is now siding with another "4G" carrier: T-Mobile USA. Shortly after T-Mob tossed off the gloves and proclaimed to be "America's largest 4G carrier," Qik has come forward with an interesting tidbit about the newfangled myTouch 4G. According to it, the "integrated T-Mobile Video Chat powered by Qik will be the first to offer integration into the native Android address book with the benefit of indicating live presence allowing customers to connect with friends and family through live video conversations and video messaging over T-Mobile's network and WiFi." We're even assured that T-Mobile Video Chat will offer "dramatically improved video quality and frame rates compared to other video calling solutions on the marketplace through deep hardware integration," and users can even see if folks in their contact book are able to video chat at a glance -- no trial and error necessary. We'll be testing this stuff out in our upcoming myTouch 4G review, but be sure to let us know how it's treating you in comments below. You know, if you're an "early adopter."
