Now through Feb. 15, Boost Mobile is allowing its subscribers access to a Valentine's Day giveaway powered by Crush or Flush, the mobile social networking platform that allows users to rate and meet people through their mobile phone.

Boost Mobile customers will have a chance to win prizes, including flat screen TVs, $100 Visa gift cards or a Disneyland vacation, in the Crush or Flush Valentine's Day giveaway sponsored by IceBreaker. Each customer will receive one entry for each day they log in to Crush or Flush from their Boost Mobile handset and can earn extra entries by adding pictures to their Crush or Flush profiles. It costs 69 cents a day to use the service, which includes anonymous chat, personalized profile filter and the Crush list.

In the first 15 days of the promotion, Boost already had 30,000 people sign up, according to Courtney Bunn, product marketing manager for Boost. The collaboration with Icebreaker works well because the company comes to the table prepared with prizes that Boost's audience will like, she says.

Boost has been offering Crush or Flush for almost a year. It can be found in the date and chat area on the deck. The service, targeted to 18- to 34-year-olds, allows users to look at pictures and Crush or Flush them, depending on their likes.

In other Boost news, the company introduced a new $1/day voice plan and dropped the price of its 600-minute premium pay-as-you-go plan from $70 to $60 a month. The new chat plan offers unlimited nights, unlimited mobile-to-mobile and a daytime rate of 10 cents a minute.

The Premium Plan offers three monthly rates - $30, $50 and now $60 – and includes unlimited nationwide Walkie-Talkie services, which makes it a great value, says Sam DiSalvo, Boost senior manager of marketing. Users can make calls to other Boost users but also to subscribers of Sprint Nextel, which owns Boost.
