I had been using my Droid3 with PDANet and FoxFi for Bluetooth tethering corrections to my R8 through my TSC2. The Droid3 is my personal phone and so I purchased Razr to be dedicated to the R8. I got it yesterday (Friday) and this morning I got it all set up and checked everything and it all worked just fine.
Then I was going through the phone getting things set up and I hit the system update button and it downloaded and installed ICS. Ever since, Foxfi will not work. At least in Bluetooth DUN. It comes up with a notice that "Bluetooth can not be started".
Since the TSC2 has wifi, I set up a connection to the razor and FoxFi using the Wifi tether instead and it seems to work fine that way (in fact it seems to connect more easily).
Anyone had similar problems and any solutions? I have googled it all afternoon and found many people are having the same issue, but solutions are lacking....
Not sure if this will help you, but there was a post on June 25, 2012 by Dale Yawn about the Razr and GPS.
