Sony Xperia Z1s case listing hints at November 26 release date

A new Amazon case listing suggests that the Sony Xperia Z1s, the much-talked about international variant of Xperia Z1 f, will be released on November 26.
Kolay, a case-maker, has started taking pre-orders for the 'Sony Xperia Z1s Black Gel' case cover and stylus pen at Amazon UK. The listing clearly reveals, "This item is due to be released on November 26, 2013." The listing is accompanied by few images that show the rumoured Xperia Z1s's front panel which looks identical to the flagship smartphone, the Xperia Z1. The rear panel image at the Amazon listing shows the primary camera placed above the LED flash nearly at the centre.

On Tuesday, Sony's upcoming Xperia Z1s was unofficially 'confirmed', thanks to an accidental listing on the company's. The official listing, which was since been pulled down, featured the yet-to-be-announced Xperia Z1s with an image and was accompanied by a tagline that said, "The best of Sony for the best of you."

Sony launched the Xperia Z1 f, a mini-variant of the flagship smartphone, the Xperia Z1, in October under Japanese operator NTT DoCoMo's winter smartphone line-up. The smartphone is likely to be released in late December 2013.

Recently, images of an unnamed Sony smartphone sporting a metal frame similar to the one seen on Sony Xperia Z1 surfaced online. The leaked images of the metal frame of the unnamed Sony smartphone revealed the usual number of ports and buttons seen on other Xperia devices - namely power, volume rocker, Micro-USB, and 3.5mm audio jack. One of the leaked images also revealed the White rear panel of the unnamed Sony smartphone, which houses the company's branding in the middle, along with an NFC logo.
