AT&T brings enhanced push-to-talk app to iPhone

Sprint changes Direct Connect plans

Sprint Nextel's Direct Connect service may not be sexy, but the push-to-talk network has a staunchly loyal following. And if Sprint knows what it's doing, it will leave the basics of Direct Connect alone.

Yet, the carrier did announce Thursday that it was tweaking the Direct Connect plans for its customers. The basic plan, which goes by the mouthful name of Unlimited Workgroup Communications, offers unlimited Direct Connect and Group Connect calls, plus unlimited text messaging, for $29.99 per month per line. For regular voice calls, you'll also get unlimited mobile-to-mobile minutes and free nights and … Read more
