Starting tomorrow, Sprint will offer an unlimited everything plan for $100. That’s unlimited unlimited voice, data, text, e-mail, Web-surfing, TV, music, GPS navigation, Direct Connect and Group Connect. The move comes after all the other carriers announced unlimited voice plans for $100, which itself was a reaction to Sprint’s limited deployment of an unlimited plan for $100. What comes next? We’re guessing family plan deals that are better than simply $200 for two lines, $300 for three lines, etc, and perhaps even price drops.
