That mainly allows for the Phone as modem bluetooth profile to be able to share with another device. I'm assuming you have Verizon, but Sprint runs on a simular network which will not allow you to share a data pack, because the carriers specify internet usage per phone active on their system. (They use the ESN and MDN to moniter usage for minutes, text, internet usage and reference that usage off the codes in the plan that's active on your account.)
