bluetooth headset for skype

[loAol]

i have an old dell with skype on it and was wondering if i could get a bluetooth adapter and headset to work with skype. i found these two on newegg:

MOTOROLA H730 Bluetooth Headset

AZiO BTD-V201 USB 2.0 Micro Bluetooth Adapter

any idea if this will work with skype?

thanks

so i noticed the bluetooth adapter is class 1 unlike the headset which is class 2.. im not sure what that means but i found an adapter that is also class 2: IOGEAR GBU421W6 Bluetooth 2.1 USB Micro Adapter

also, does the headset work with an iphone 3gs?
