T-Mobile has its T-Mobile Tuesdays, Verizon has its VerizonUp and AT&T has its AT&T Thanks. After long being the only carrier without one, Sprint on Tuesday is finally getting into the rewards game. Called simply My Sprint Rewards, the new program echoes the others by offering perks, contests and other goodies to those who subscribe to Sprint's service. Sprint users can check the offers by downloading the My Sprint Rewards app for iOS or Android and logging into their accounts. There is no cost to join the program with Sprint promising "exclusive deals" from the carrier as well as from a "large variety of well-known brands in apparel, auto, beauty, electronics, health, home, sports, travel and more."
