Mobile messaging and more...for free. I'm Fred Fishkin with technology Boot Camp, a report on gadgets and gear. If you have an iPhone, Android or Blackberry smartphone, a company called Centrl...that's C E N T R L....has an app...that displays not only where you are...to friends and family...but lets you communicate for free. It works from any Web browser as well...and links with social networks. The company's Larry Richenstein ...

"You can open up Centrl through any of the major social networks and you don't need to set up a new profile. It picks up the profile from that social network. And you can invite your friends and unlike a lot of other ones where you have to go and ask your friends to join and set up a whole new profile, you don't have to do that. They can come in and be communicating with you right away."

It's free. The plan is to make money through location based advertising...that will use digital coupons. You can find more info at Centrl.com. You can find us with archives, interviews and more at BootCamp.com. I'm Fred Fishkin.
