I just bought a used N810 and I wasn't paying attention to the sale post and after paying for it, noticed it doesn't come with the headset. Which makes the device nearly useless for me, as I was primarily purchasing this to use with Skype so I wouldn't be tied to my laptop. I have a bluetooth headset for my mobile phone, a Motorola H505. Can I unpair this from my phone and pair it to the N810 or can I have it paired to both?

If I need to purchase a headset, what do you recommend and where can I get one from? I don't mind a corded headset.

Thanks!
