Well, there's also corporate discounts. I currently get 10% off AT&T through Ohio State and I know that other companies give bigger discounts. My one friend has Sprint and his dad gets like a 20% discount. Another has Verizon and he gets like a 28% discount. I'm about to switch to T-Mobile and I found out that I get a 15% discount I think.
Still. Nobody should be on Sprint in 2013 using a smartphone. Even dialup surpasses them. They were once a great cell PHONE company. To bad they can't deliver. I feel bad for anyone using them, when T-Mobile EDGE would be better.
