With phone specifications often reaching a terminal velocity before the next new technology or trend, giving your hardware a differentiator can be hard. Sharp's new AQUOS Serie mini SHL24, however, is having a stab at a couple. Firstly, the TV maker is leveraging its IGZO screen tech, and spicing it up by cramming a full (1080p) HD display into the 4.5-inch panel -- that's almost 490 PPI. Secondly, in what it's calling an EDGEST design, the AQUOS Serie mini SHL24 seems to have some of the thinnest bezels we've seen for some time (bar the bottom one where the buttons are) making that screen really take pride of place. Thirdly? Colors of course! As for the rest of the specification, well it's not too shabby either. First up, it's running Android Jelly Bean (4.2), sports a 13-megapixel camera, 16GB of storage (with an SD card slot) and a Snapdragon (MSM8974) quad-core processor -- clocked at around 2.2GHz. Oh, and it's even waterproofed to IPX57 standards. Those are quite a few boxes ticked. But, sadly there's one biggie that currently remains empty -- as far as we can see right now, this is a Japan-only device. Sorry.
