With the news today of the Samsung Galaxy S III’s impending U.S. release, it would be easy for HTC to take the day off and let Samsung enjoy the hype surrounding its new flagship Android device. However, HTC has its own cutting-edge Android smartphone, one that it thinks is just as good, if not better, than Samsung’s. To show off the new HTC EVO 4G LTE, Sprint and HTC have teamed for a new ad campaign highlighting the smartphone’s Beats audio and Sprint’s unlimited data plans.

The campaign, called “Unlimited Love Unlimited EVO,” will be featured on TV, on the web, on mobile devices, and in print. There will also be a “socially driven” sweepstakes taking place through Facebook.

“The creative for this campaign evokes an emotional response from the viewer,” said Caralene Robinson, vice president for Brand Strategy and Marketing Communications at Sprint. “The HTC EVO family of phones has a loyal following with millions of fans. They love their EVO devices, and this campaign highlights many of HTC EVO 4G LTE’s capabilities, including an 8-megapixel camera with rapid-fire, continuous shooting — so getting the perfect shot is simple — and a sound experience unrivaled on a smartphone. Those new features come to life in this campaign and we are encouraging viewers to tell us what they love most about the phone.”

A TV spot for the EVO 4G has already been released, and can be seen below. Sprint states that the ad is a “love song” that EVO users are singing to their phones using music apps. The song is actually a version of a Wilco song called “I’m Always in Love.”

If you look closely, you can see fine print near the bottom of the ad admitting that Sprint’s 4G LTE network has not yet launched, making the phones 4G capabilities a moot point. Also, when Sprint’s 4G network does launch this summer, only Atlanta, Baltimore, Dallas, Houston, Kansas City, and San Antonio will receive the service. The good news for those cities, though, is that Sprint has announced its unlimited data plans will carry over to its 4G service.
