Finally!!!!!!!
I know I'm a little late to the party, but Hella YeA. I just loaded 4.2 on my Sprint 8703e and am now able to pair with my Macbook and use the Phone as Modem (PAM) throught the Bluetooth. I'm so fricken excited I could just scream...but that might be a little gay so I'll keep it in check. This has been one of the biggest downsides to using a BB with the Mac's. Before I had to go into Parrallesl and use the Sprint Connection Manager to go throught the back to door to get internet function on the Mac side (a real pain), not any more.
I'm really just posting this so that other other 8703 / Mac users might find the info when doing a search on the subject. I supersingly didn't find anything when I was searching around so now maybe they will. You would think that this would be all over the place as it is such a boone to us Mac users.
P.S. No problems with BB Maps / Googlemaps / or the GPS what so ever
