I successfully used my imac to make calls through my iphone using bluephoneelite. I guess the new software updates and SL helped in some way to crush the bugs.Also bluephoneelite updated their software too. One thing cool is that, once set up and someone calls, you get this option on iphone to listen to your caller via mac, iphone, speakers. So far so good. I have yet to try this on macbookpro bluetooth You cant text using the software though since its not supported yet.
