We revealed the full details of the HTC One Mini yesterday, but now the Taiwanese company has made the smaller phone's official debut. The One Mini is a 4.3-inch counterpart to the larger One, alike in design if not specifications: the general look and shape of the flagship is preserved, along with all the software features, plus the Ultrapixel rear camera and "BoomSound" front-facing stereo speakers. HTC plans a worldwide rollout of the One Mini starting in August and continuing into September, with no prices available yet.

The CPU is a less intense Qualcomm Snapdragon dual-core running at 1.4Ghz, paired to a more pedestrian 1GB of RAM. Storage options are limited to 16GB, and like the flagship one, there's no MicroSD card slot. HTC isn't saying how many "Ultrapixels" are used on the rear camera, but since the F-stop value is an impressive 2.0, it should still take pretty good stills. The front-facing camera is 1.6MP. The Android version isn't mentioned, but since features like Blinkfeed and Zoe are being highlighted, we're guessing it's the same build of 4.2 that the One has been enjoying for months.

The smaller screen gets a naturally lower resolution: the LCD has been bumped down to a still-respectable 720p. Impressively, the body uses the same aluminum design as the larger One, with only a few visual cues showing the difference - note the lack of a seam running to the rear camera, and the LED flash has been moved above the camera module.

We know that AT&T is getting a localized LTE version of the phone, and you can bet on both HSPA+ and LTE versions of the phone being made available to the larger international market. Beyond that, there's no news of American carriers. Since the original One was made available to all four major cellular providers (even if Verizon is taking their sweet time), it's more than likely that at least one more will jump onboard.
