The Logitech for IPOD headphones work fine with this patch. As mentioned before, the Wi-Fi at the same time causes stuttering and is not usable. I had the same problem on the IPAQ 5550 I had with the HP Bluetooth headphones (which are the same as the Logitech IPOD model except these have a dongle to go with an IPOD). By the way, I got these for $85.99 at Newegg and they have a $50.00 rebate through April.

The IPAQ would work with the bluetooth headphones AND wi-fi when I used an external 802.11 card in the expansion slot. So maybe if there is a mini-SD 802.11 card out there it might work along with bluetooth without stuttering.

(and I just tested them with the laptop and Bluetooth 2.0 dongle and they work plus as an added bonus, the dongle works great with my SD card MP3 player too).
