Sprint has announced (via 9to5Mac) that it will be offering $100 off on both the iPhone 5s and iPhone 5c to new customers who port their number to the carrier, dropping the price of the 16GB iPhone 5c to $0 and the price of the 16GB iPhone 5s to $99 with a two-year contract.
The move comes shortly after news leaked of Sprint's upcoming "One Up" frequent device upgrade program, which will allow customers to upgrade their phones and tablets at regular intervals. It also comes four days after T-Mobile announced that it will be offering the iPhone 5c for $0 down and iPhone 5s for $99 down, although Sprint's prices only apply to new customers while T-Mobile's pricing applies to current and new customers.
With the promotion, which ends on October 10, 2013, the iPhone 5c will cost $0 for the 16GB model and $99 for the 32GB model while the iPhone 5s will cost $99 for the 16GB model, $199 for the 32GB model and $299 for the 64GB model. The iPhone 4s will still be $0.
The iPhone 5c can be pre-ordered immediately from Sprint's website, and the iPhone 5s will be available for order beginning on Friday, September 20.
