Technology experts Meghan Wilker and Nancy Lyons of the Geek Girls Guide entered the FM107 studio for our Shop Girls radio interview pecking away at their iPhones. The minute the On Air light went on, they flipped me: recording our interview on one of those adorable little Flip video cams, which they consider one of the best things to happen to mothers since all-day kindergarten. You want to be friends with these two. They're with-it, working moms on the cutting edge of technology, but are able to talk about, well, geeky matters in an entirely approachable way. Here are a couple of the cool new things they told me about for iPhone devotees: The Owle Bubo, an attachment that turns the iPhone 3GS into a higher quality, more flexible video camera, and a couple of must-have apps that moms can feel good about using to bribe - er, educate - young kids: Baby Flash Cards and the pro-vegie game Pickin' Time. Geek Girls speak fashion too: they turned me on to Polyvore, a cool website where you can catch up on the hottest trends and actually mix and match pieces to create looks. Want more?
