It's funny I came across this thread, because just today I learned how to transfer files between my phone and laptop. I'm running stock 2.1 on my Hero and Windows 7 on my laptop. When I wanted to send a file from my laptop, I right-clicked the file, and under the "send to" tab, i selected bluetooth. The first time i did it, I had to set up my phone and laptop with some verification code, but after that first time it worked great! As far as sending a file to my laptop, the only thing I've really tried it with is a picture from my phone. I selected the picture, pressed the "menu" button on my phone, and clicked "share" and you should be able to select your laptop and from there it's self explanatory. I really hope this helps! I think it's a really cool feature!
