Sony has quietly confirmed the existence of a beefed-up successor to its Xperia S smartphone, posting details of the Xperia SL on its website. The new device, which was revealed in leaked pictures at the beginning of this month, boosts the S's Snapdragon S3 CPU from 1.5GHz to 1.7GHz and adds two new color options, pink and silver. The Xperia SL will ship with Android 4.0 Ice Cream Sandwich, matching the software which rolled out to existing Xperia S devices in late June, and will retain its progenitor's 12.1-megapixel rear-facing camera and 4.3-inch, 720p display. Sony has not yet revealed any information on availability or pricing.
