As one rumour closes, another one kicks off. Yes, we've had the official launch of the Samsung Galaxy S4 Active and in its place, filed under 'very likely', comes the HTC One mini, complete with photo evidence.Well, that's the name currently being used. It has been known as the HTC M4 in the past, when it was just a rumour with specification. But that sounds more like an in-house code name. The HTC One mini sounds…well, it sounds right. It's a mini smartphone from HTC. Can you think of a better name?The photos come from Estonian site forte.delfi.ee, which seems to have got very hands on with the miniature handset. As for the specification, it seems in line with those previous rumours, which points to a 4.3-inch device with 720p display, a dual-core processor, 2GB RAM, 16GB internal storage and a 4-megapixel camera complete with UltraPixel technology. The same source claims the HTC One mini (or whatever name is settled on) will have an August release date, selling for around €400 in Europe. We'll wait and see if that's true. But with all this evidence, we can't see it not being really.
