For all of you familiar with the bluetooth headset problem I am curious to know if 4.1 fixes this? I have two bluetooth headsets and have not updated my ip4 yet. My streaming set (which i use to listen to music) constantly glitches and warps the sound. My other bluetooth will connect and reconnect constantly as I enter and leave wi-fi areas... very annoying, but I dont want to upgrade to 4.1 unless i am sure it will fix this issue.
