Alright we can stop playing the guessing game: it’s Feburary 24th and Sprint has officially announced their latest phone. (We did hear about this yesterday, though.) No, it’s not Android – we originally warned you that Android isn’t the only smartphone operating system in the world. (Bummer, right?) It’s a Windows Phone 7 device called the HTC Arrive. We’re not going to say much more than that on it as we’re not a Windows site, but this was just a quickie to inform you guys that the EVO and Epic 4G are still the best Android phones on Sprint’s network until… we don’t know. Let’s hope CTIA brings the goods. [Sprint]
