Remember the good old days of using your PTT (Push To Talk ) on your Nextel. After smartphones hit the mainstream everyone put away their Nextels and moved on to Blackberrys (and then we move on from those).  Well Sprint is trying to keep the Nextel spirit alive by having a PTT option on your Android device as an app.  How useful will it be who knows but just having the option is good enough.
