Also depending on which rom build of NFSFAN your running there was a problem with bluetooth on an older build which was fixed on the newer builds....
Are you running his recent version? 1.05-Alltel

I have my gfs touch running on this rom and its works great with her bluetooth no problems.
Also you might wanna try a reflash.
