The Xperia S is a mere six months old. Yet, rumor has it that Sony is already prepping a refresh, dubbed the Xperia SL. The handset surfaced at the Indonesian POSTEL site (which appears to be something akin to the FCC), bearing the model number LT26ii. That seemingly random collection of letters and numbers actually reinforces the suspicion that the SL will replace the S, which goes by LT26i -- for those fascinated by nondescript naming systems. What else can we tell you about the device? Well... a whole lot of nothing unfortunately. Chances are it will be mostly a minor spec bump -- perhaps a quad-core CPU and a better camera. For now, though, you'll just have to wait and play the guessing game with the rest of us.
