Yeah, Microsoft has said that they’ve planned on releasing their “NoDo” updates. They gave you “Early March” as the release date. They forgot to tell you that they’re not releasing it to you, but to your carriers. According to an update on the Windows Phone Team Blog, they’ve already gotten the update out to your carriers.
The carriers now get to take it and test it “for the customers” which means they’re making sure there’s no way to get free wifi hotspots. For info on your phone, hit up the source link. It will tell you what stage your phone is at, and what that means.
