At an event in New Orleans today touting its so-called Network Vision infrastructure plan, Sprint spent time talking about its previously leaked Direct Connect Now product, an Android app that will bring push-to-talk interoperability to smartphones in the carrier's lineup. Though Sprint has (and will continue to have) hardware-enabled Direct Connect phones in its portfolio, the benefits of a pure software solution are obvious: users who need PTT functionality can select from a larger variety of devices and be assured of interoperability with coworkers who are using true PTT handsets. There's no word on a release date yet, but Sprint will be making the app available in Google Play.
