That Sprint is releasing LTE phones (the Evo, the LG Viper, and the Galaxy Nexus) without an actual 4G LTE network in place is a bit frustrating. While the company has disclosed the initial six cities for launch (Atlanta, Baltimore, Dallas, Houston, Kansas City and San Antonio), it has not said when these networks will turn on. And unless you live in one of those cities, you'll find it hard to get excited about LTE. Sprint's 3G network feels painfully slow, too, especially when you compare it to other carriers' 4G networks. Sprint has announced that it will release 15 more 4G devices, most of them handsets. Unless you are 100 percent committed to the Evo legacy or are dying to upgrade your phone, I'd hold off on buying the Evo until you know that you'll get LTE or have seen what else is available before locking into a two-year contract.
