As title states my iphone 4 was recently updated to absinthe 5.1.1 before 6 came out. I have a bluetooth device that was working before with everything on absinthe 5.0.1 however, no longer makes or recieves calls or can take in any input using the device. I have not tried it on another smartphone yet because I do not have that at my disposal. The bluetooth was functioning before perfectly but no longer after upgrade. My question is this - is there a way to fix this without redoing everything or is this a problem anyone else is having? Thank you for any interest in this problem and I am also sorry if I posted this in the wrong forum area.
