This is the future, we tell ya! Not the immediate future, mind you, as it's a humble prototype with no commercial intentions behind it, but it sure looks like the right direction for us to be moving in. SK Telecom has somehow fit a processing chip, memory, a gigabyte of flash storage and Google's Android OS onto the SIM you see above. The concept is pure genius -- you store your entire mobile environment on the SIM card, including your contacts, operating system and customizations, which should then allow you to switch up your handset hardware as often as you like without the need to set it up anew each and every time. We'll head to SK Telecom's booth at MWC later today for a closer look, but for now you should click past the break for a video.
