AT&T Adds Wi-Fi Support to Its Enhanced PTT Service
Replying to: But is it secure? And how about a head-to-head comparo? by cellphonesaretools

A head-to-head would be interesting. I can tell you that in my area, Sprint QChat is as fast and reliable. The only downside is a QChat session still ties up the phoneline like Direct Connect.
My guess is you don't miss regular or PTT calls with AT&T's system. If Sprint was looking to upgrade, you'd think that feature would be a must. Below is a breakdown of what calls you'd miss while doing other things on the phone:
-Active data session: Cellular calls
-PTT session: Cellular calls
-Cellular calls: PTT calls (IMs and MMSs are delayed)
Maybe when Nextel becomes 4G LTE, these issues will be resolved on future handsets.
