I too am a Windows Phone fan and a loyal Sprint customer. I've been trying to get a straight answer from Sprint/Microsoft/Samsung and haven't had any luck, at least not officially. The one that seemed to make the most sense was that Samsung always wants to make sure that they release a stable version of software on their phones. Beyond that, nothing specific about the Ativ S Neo. Now, I understand from several posts in other forums that the Sprint HTC 8XT HAS Windows 8 GDR3. I have also seen a couple of posts in other forums that Sprint reps have confirmed that Sprint will never get the GDR3 update for the S Neo. I just want to know the situation with my phone from whom ever that can tell me.
Just for giggles I went to the Samsung site and asked about the updates for the Neo. First thing I noticed SPH-I800 isn't even listed on there site, I had to tell the CSR which phone I had. And as you might expect the answer they gave was "We don't know when or if it will happen!" Gotta love it! LOL
