So, if I currently have an AT&T account with my Pearl (which is linked to a family plan with my daughter), I can now buy this 8310 from Amazon at the price quoted, and just extend my current contract which still has about 13 months left? If the answer is yes, then this is a no brain-er for me. Can someone chime in on the facts? I wouldn't want to be subject to any additional fees by changing the terms of my current deal.
