That oft-rumored successor to the Sony Xperia S smartphone, the Xperia SL? Sony's now officially listing the 4.3-inch GSM device as "coming soon" on its website, along with full details and specs. As it turns out, the initial leaks were correct -- the SL is a slight refresh of the S, differentiating itself with an additional duo of color choices (silver and pink), a faster dual-core 1.7GHz Snapdragon S3 CPU and Android Ice Cream Sandwich (up from a 1.5Ghz processor and Gingerbread). Aside from all that, it's the same media-focused phone, loaded with the same 720p display and 12.1-megapixel shooter, that we reviewed in March. We can't say we're overly excited, but you'll find more info from Sony at the source link below if you're interested.
