If you want to buy an HTC One without a contract, HTC is selling an unlocked version of the smartphone for $574. The unlocked version of the phone will have 32GB of internal storage.
Earlier this month, HTC also started selling the HTC One Developers Edition smartphone for $649. That model costs $649 with 64GB of internal storage and an unlocked boot-loader. This allows developers to modify the phone with customized applications at the root level.
The HTC One is available at a reduced price through a contract with AT&T, Sprint, and T-Mobile. Verizon is expected to add the phone to their line-up in the near future as well.
