The black One S goes on sale now via T-Mobile.com and the carrier is bringing in a limited time deal to get the phone for free after a mail-in rebate if you sign a 2-year contract.
Overall, the One S right now runs on Android 4.0 ICS, but HTC has promised a Jelly Bean update soon. It features a 1.5GHz dual-core Snapdragon S4, and an 8-megapixel camera. Its weakest point seems to be the qHD resolution on the screen, but if you are not a screen perfectionist it should still be fine, especially for that price of free. The display is 4.3 inches and of the AMOLED kind.
