We've been back and forth with the Push to Talk info for a few weeks, but it now has finally made its way to Verizon (for real). Tour 9630 users can now officially add the service to their existing BlackBerry data plan. You can either call up customer service, or head to the personal or business account pages to add the service. Once you have it all set up, you'll be able to download the app and use the left convenience key to talk away. The PTT service is $5/month, but a limited free-trial is available for qualifying customers. Head over to verizonwireless.com for more or to add PTT to your account.
