Alright, so this isn't about Pocket Pcs, but you guys will know. I have a Nokia 6300, and it has a handsfree jack. The included headset also enables FM radio on the device.
I have a 2gb MicroSD card (Thanks Pricegrabber!) and the phone has a great mp3 player. I tried a couple headphone adapters at RadioShack. One didn't work at all, one made the phone react, saying "Headset detected, use microphone?"
I hit no and put on the headphones, and there was only sound from the left side. I couln't get it to askme the mic question again.
