I too am wondering if this newer better more awesome update does fix a Bluetooth issue I have been having. I know that all phones suffer some signal loss while they are close/contact with skin.
I have been having a problem with my Blueant T1 and my HTC Senation 4g. When I have the phone in my phone case attached to my belt, I sometimes do not get a connection to my headset. I can answer my call, but I can not hear them. When I have the phone laying down on a table, I can get a max distance of 8ft(No walls between myself and the phone) before I start hearing skipping in either a call/music/video.
I have checked the contacts in the back where the wifi/Bluetooth connect to the back and I have contacted HTC for a replacement back. I currently have a Nexus One that I can go at least 20ft before I start getting some type of interference. I am curious if anyone has this, fixed this, or can verify this.
Thanks! Its not a make or break type of deal, nor is it specifically a ROM issue, just curious.
