One of the things I like about the Dell Axim X50V Pocket PC as a podcaster is the fact that it supports the Bluetooth Headset/Handsfree profiles. That means that you can pair a Bluetooth headset to the X50, and pipe all system audio through the headset, including the ability to record. The quality isn’t the greatest, but it’s usable for mobile podcast recording, and it’s the only non-phone Pocket PC I know that supports this.
A coworker and I were experimenting with pairing a Bluetooth headset to his X50V, which he upgraded to Windows Mobile 5. We could get the two paired OK, but Windows Mobile 5 includes a new Bluetooth stack (from Microsoft, I believe, instead of the Widcomm stack on WM2005 X50s). We weren’t able to get any audio to come through once they were paired. To make sure, I paired the headset with my WM2003 X50V, and the audio functionality worked just like I remembered it.
So, it seems that if you want or need the ability to pipe audio through a Bluetooth headset from a Dell Axim X50, you’ll need to forego the upgrade to Windows Mobile 5. If you have an X51, which comes with WM5, you’re probably out of luck completely.
Yay for removing features in newer versions of software! GG Dell! *sigh*
