Hey guys, been quite some time i visited this thread and the amount of information currently available is great! Probably the most comprehensive Nokia 5800 XM Manual Guide on the Net

Just a small question in case you guys faced the same issue before. I just bought B-Speech Calypso SP Bluetooth Headset which supports A2DP profile and paired it with my Nokia 5800. The Volume Up, Down and Play buttons on the headset work fine with my Nokia 5800, but the Next and Previous Track buttons do not work at all. There is just a beep when pressed, but the track does not move forward or backwards. My phone's firmware is already updated to the latest.

Hope somebody can offer a solution as it's a good headset, but this small issue is really, really annoying. Thanks a lot guys and have a nice day

Before was just using the regular wired Nokia earphones with very old firmware. I updated to latest firmware before pairing the BT Headset, maybe earlier firmware were able to use, I'm not sure. Thinking of selling it off as still very new, quite useless if have to take out phone everytime wanna change track.
