Sprint's annual upgrade program 'One Up' available today

For the overeager phone fans

Sprint One Up

Sprint officially joins the other upgrade plans by announcing today that its annual program "One Up" is now available for new and old customers.

One Up starts at $65, and offers customers a monthly installment plan to upgrade their smartphone every 12 months on top of unlimited talk, text and high speed data.

You can also get an introductory $15 discount on its Unlimited, My Way, and All-In plans, one of which must be selected for One Up.

The price point is a bit higher than previously reported, though Sprint notes that customers will see a savings of $45 a month on One Up "compared to similar plans from AT&T and Verizon."

The plan also strategically launches the same day as the iPhone 5S and iPhone 5C, just in time for those eager Apple fanatics to trade-in.

A brief how-to

To take part of the upgrade, you need to buy an eligible smartphone or tablet and agree to 24 monthly installments - no down payment is needed on certain phones, and there aren't any finance fees.

After 12 months of consecutive payments, you can then upgrade your device to a new phone or tablet.
