Though it has not been officially announced with any carrier in the US, unlocked versions of the Samsung Galaxy S3 Mini have surreptitiously cropped up on Amazon. The price? A mere $409.95.

The phone was introduced in October, and it features a Super AMOLED 4-inch display, 5MP rear-facing camera, 1GB of RAM, 8GB of internal memory, and dual-core 1GHz processor. The S3 Mini also comes with Samsung’s Touch Wiz user interface laid over Android 4.1 Jelly Bean. That is unlike a majority of the full-size Galaxy S3s available stateside, which come with Android 4.0.4 Ice Cream Sandwich.

The Galaxy S3 Mini is essentially a smaller version of the Galaxy S3. It measures approximately 121.6 x 63 x 9.9 mm, while its bigger brother measures in at 136 x 70.6 x 8.6 mm. It doesn't offer LTE support and its frequency differences mean that it won’t work optimally on T-Mobile’s HSPA+ network.

While the S3 Mini has been long regarded as the Tweedledee to the Galaxy S3’s Tweedledum within the Android rumor mill, it’s still unclear whether the Galaxy Express and the S3 Mini are the same handset or whether the former was meant to be the US version of the latter. We reached out to both Samsung and AT&T for comment. Samsung did not reply as of publication time, but AT&T said that it had no knowledge of an S3 Mini in its lineup of available phones.

So far, it looks like the phones are selling fast on Amazon. As of this writing, only ten were left in stock. If you are interested in an unlocked, smaller version of the S3, this might be a good time to nab one.
