I have a mono (non A2DP) plantronics 520 headset, and it actually pairs with the ipad2 wifi and can be used with telephony apps. Right now I tested it with GoogleVoice and TextFree with Voice (non Ipad version). I also tested it with skype, but skype didnt seem to recognize it. Just thought was kind of cool and didn't see it posted so wanted to share. Also http://support.apple.com/kb/ht3647 shows ipad 2 has handsfree profile.
