We know all that Radio Shack is store that offer discounts for iPhones but it seems that it is not the only one who make this it, also Best Buy will offer free iPhone 3GS on Friday, December 10, 2010. According to BGR report that this offer is valid to both new lines, additional lines, and also qualified upgrades.

We have been told that all stores have inventory levels to support the promotion, and it’s an instant rebate type deal.

So hurry up guys because it is limited  to one unit per customer only. Only the handset (iPhone 3GS) is offered as free, you will of course have to pay for the AT&T contract.
