its free to make someone smile for Valentine's Day! you can send from web/mobile to web/mobile AND reply. Freeeee (tho your carrier may charge you data fees or similar)
its at http://www.gridbloc.com/greetings and works especially well on sonyericcsons (p800/900, t610, even trusty ol' t68s) and mosft smartphones. the cards require you be able to click a link in the SMS, its free so just give it a try.
