With a reliable source to trust, the logos of Sprint’s Nexus S 4G and the Motorola Xoom tablet have leaked online, ahead of CTIA Wireless 2011. Nexus S 4G will hit Sprint’s network soon, with a CTIA announcement most likely going down next week. The image below shows the Xoom slate with the Sprint branding on, another device we’ll see at the tech show next week.

No info on what prices will be applied, or launch dates, unless you want to sleep on it and wait for the CTIA show. We’ve heard that Sprint will be showing WiFi-only and WiMAX 4G versions of the Motorola Xoom and we’re really curious how well they’ll do in comparison with the Verizon version. Also, will the Sprint slates get Adobe Flash Player 10.2 as an update, like the VZW Xooms?
