Upgrades used to mean a 2 year contract and a "sweet" deal on a new phone. Now you still have to sign a 2 year deal and just end up paying in installments? Can anyone actually explain why a person who uses less than 3 GB of data and has one line- therefore does not qualify for any other discounts- even bother? I can switch and get $500 from another carrier that is only $10 more per month...?
