Since Apple enabled the Bluetooth chip inside the second generation iPod touches in 3.0 I need suggestions on a cheap bluetooth headset, as I never purchased one before and therefore have little to no experience. I don't really care about A2DP unless I can get it for under $30 bucks. So something cheap. Also, can I use the headset's mic to record audio in the Voice Memo app? Or am I stuck with purchasing Apple's earbuds w/ mic?
