I haven't seen a thread about this yet, but is anyone else experiencing this right now? It seems Sprints 4G WiMax isn't "authenticated" anymore to use the Play Store. So when you download apps, you need to be on 3G or WiFi...making downloads super slow (for me atleast) I've seen some other websites saying its Google's problem, and some people saying its Sprints problem. So of course each company is blaming each other. So anyone find a fix for this yet?
