Sprint today announced that it is finalizing the software to upgrade the HTC Evo 4G to Android 2.2. Sprint's other Android phones, the HTC Hero and Samsung Moment, will not receive the system update. Sprint says its Android 2.2 upgrade will offer Flash 10x support, voice dialing over Bluetooth and the ability to store apps on external memory, among other features. The upgrade should be available "in the near future."
