Walt Mossberg reviews the Sprint Evo 4G: The new phone works on 3G and 4G WiMax networks, and Mossberg tested it in Sprint's oldest WiMax market, Baltimore, and in a new on in D.C. While he notes that he saw the fastest cell performance ever, that still wasn't saying much--he found speeds to be far below the maximum.
Battery life is the real issue. With 4G active, he couldn't get through a day on a full charge. Storage for third-party apps and data is strange. Mossberg writes that there's just 400 MB out of 9 GB available. The phone runs Android, and has a Wi-Fi hotspot feature and tethering available ($30 more per month).
