Best Buy has outed the LG Optimus Slider today by listing the device as “coming soon” on their website. We thought we had this pegged for Sprint but it looks like they may have passed on this device, instead handing it off to Virgin Mobile. While we don’t have too many details to give, we can tell you that just like the Slider’s other Optimus cousins, the device will feature largely the same specs but this time with a full slide-out QWERTY keyboard. Other notable specs include a 3.2-inch display, 3MP camera and running on Android 2.3 Gingerbread. The Optimus Slider will carry a very affordable $200 price tag for a contract-free plan on Virgin Mobile. We’ll provide you with more details as soon as this device is officially announced.
