In March the CEOs of Sprint, Verizon and AT&T took the stage at CTIA in Orlando for a lively discussion about the state of the mobile ecosystem and its future. The keynote was affable with an undertone of drama, coming two days after AT&T announced that it was acquiring T-Mobile for $39 billion.

The CEOs returned to the stage today at the CTIA Enterprise & Apps conference in San Diego. A lot has changed from March. Sprint has sued AT&T to prevent the T-Mobile merger and is fighting for its livelihood as a major U.S. carrier. Sprint CEO Dan Hesse took a couple swipes at AT&T head man Ralph de la Vega but overall the carriers spoke about working together and how they are pushing the bounds of mobile innovation in the United States.
