Verizon Push-To-Talk application for BlackBerry smartphones

Verizon has made good on its word to introduce the Push-To-Talk application for BlackBerry smartphones, where this free to download application can be maintained via a $5 monthly fee. With Verizon’s BlackBerry PTT app, one will be able to make unlimited nationwide calls to other PTT devices, with key features being its ability to make group calls with up to 50 participants (great to have a mass relative meeting), Presence to check out who is available for PTT calls, easy management of Push to Talk contacts, and even the ability to access email and surf the Internet when you’re on a Push to Talk call. Anyone given it a go yet, and how do you find it?
