I have 3.0GM with no hacks or anything done to my OS. My friend posted this on twitter today and I tried it and it worked for me. For those who have 3.0 use this link and it enables it in your settings. You must open the link on your iPhone using Safari. I have a unibody 13" macbook and it paired. If this was posted before sorry. http://tr.im/oGhq Update title since people kept asking if it enables MMS, NO IT DOES NOT ENABLE MMS! Only Tethering.
