This looks to be an interesting new service for those on the go who can’t live without coupons. Mashable, a blog covering Web 2.0 startups, brings us details about Cellfire, a site offering a downloadable application for cell phones which “provides discount coupons for T.G.I. Friday’s, Hollywood Video and other major brands.”

After you select the location you are visiting, you fire up the application and select the coupon you want. You then show the coupon to the cashier, who enters the on-screen code to give you the discount. The service is reportedly free to use, minus standard carrier data transfer fees. The service is currently only available with select Cingular phones.
