Sweeet!
I'm on T-Mobile FlexPay, and I'm glad to hear other carriers are considering similar programs. Our (prepaid customers) money is just as good as anyone elses!
I loved how easy it was to walk in the store and buy the phone without any contract/credit check hassles. I've been using prepaid phones for several years and will probably NEVER consider signing a contract. This is a big step towards removing the stigma from prepaid service. Just because I don't want to sign a contract doesn't mean I'm a deadbeat.
