The SpeedDate iPhone application is available for free download from the online dating service, SpeedDate.com. The app allows members to “wink” and “flirt” with other members (apparently a less subtle version of the Facebook poke) as well as create a new profile or edit an existing one.
Once you get your profile set up (takes about a minute) you can view a slide show of singles in your area on your iPhone. The site is free for the first 7 days (should be enough to set up your Valentine’s Day), but after that it’s $60 a month. I’m thinking digital cable is your better option.
