Here I found on the App World a really interesting but at the same time, very useful and nice app and you will see why. Actually, its name should tell you almost everything about this app but I will also describe it below.

Push2Talk converts your phone into a walkie talkie so you should already be amazed about this. If the description of this app, you need to pay only once (the moment when you buy the app) and there are no hidden fees which are usually very annoying when you find them.

Push2Talk uses the BlackBerry PIN messages to communicate. You might expect for this app just to record your voice and then send it as a message. Well, you would probably be able to do that without this app and if it would be that way, this app woouldn't deserve that name and it wouldn't replace a walkie talkie. Yes, this app sends your voice to another BlackBerry device in real time using an advance algoritm to do that which is very awesome. Probably this is also the reason of why this app costs $4.99 but it's still a small price for such an awesome app.

You can buy it from here.
