Samsung SPH-I800 may be the ATIV S variant for Sprint
Earlier this year, Sprint confirmed that it was willing to give Windows Phone another chance and promised to launch handsets running Microsoft's platform this summer. What the carrier has yet to clarify, however, is which phones exactly it is planning on releasing on its network. All we know is that a couple of WP8 smartphones are to be released on Sprint in the near future – one made by Samsung and the other by HTC.
But a tiny piece of this whole puzzle has apparently surfaced on the web. The Bluetooth SIG has certified a Samsung smartphone with a model name SPH-I800, which is clearly headed to Sprint. We know that since "SPH" is a model name prefix used by the carrier. And while the database entry does not specify what platform runs on the device, clues found online indicate that the smartphone is powered by Windows Phone 8.
Rumor has it that Sprint will be offering the Samsung ATIV S as one of its two first Windows Phone 8 smartphones, so that might be the device behind this mysterious model number. But whether that's really the case or not will be known after Sprint itself makes an official statement on the matter.
