AT&T will center a Valentine's Day promotion around the release of Enrique Iglesias' Spanish-language greatest hits album due Mar. 25.

An exclusive mastertone cut of "Dónde Están Corazón," one of two new tracks on the Universal Latino release, will be offered by the wireless company. AT&T will incorporate the song in national TV and radio spots Jan. 21 - Feb. 14.

The video for the song, plus a text code to download the ringtone and ringback, will be featured in the TV commercial for the promotion, which will also encompass print advertising in certain markets.
