Best Buy has quietly started up a new promo that gives away a free 3G or 4G router with an iPad, store visitors discovered on Sunday. Those who buy any Wi-Fi iPad and start up a two-year data plan can get either a MiFi on AT&T, a Fivespot on Verizon or an Overdrive on Sprint. Terms spotted by 9to5Mac reveal the discounts are due to end January 2.
