Sprint has just announced the launch of Music Plus – a music player, music library manager, ringtone manager and music store all in one app. For folks who don’t have an MP3 player or always leave them at home but have their phones with them instead, Music Plus is for you. “Sprint Music Plus is an easy way for our customers to discover new music and tones and manage all of their music content in one convenient place,” according to Sean Khurana, vice president-consumer product marketing at Sprint. Taking full advantage of Sprint’s 4G WiMAX network, downloading music is not going to be much a problem, though you should keep an eye out on your phone’s battery life. Sprint Music Plus is available for Sprint users with Android, BlackBerry and Java feature phones launched after May 2010. Java feature phones launched before May 2010 will only have access to ringtones and ringback tones.
