Just upgraded to my first smartphone and love the IPhone 5, but not a fan of the $30 upgrade fee. My blue tooth device does not work as well with the phone as it did with my previous phone. It is not clear and the voice quality is poor. I did some research and it seems this is a known issue. Please let me know if you have had success with a particular blue tooth ear device and your IPhone. Thanks in advance!!!!
I have Jawbone, It's expensive, but it works well. It lets me know, when someone calls me, what the phone number is, right in my ear! and is very clear. Mine is the Jawbone Icon.
