PTT - Symbian OS
Palringo works by integrating with several existing, popular messaging services including AIM, Google Talk, Yahoo! Messenger, Gadu Gadu, ICQ, Jabber and Windows Live Messenger.
Palringo presents a Symbian user's IM contacts in a single, combined, presence-aware list, whichever IM service their contacts are using. This eliminates any need to switch between different IM applications in order to send a message to different contacts. Sending a voice, picture or text message are single-click operations.
That's just the start though! See anything interesting? Just snap a photo and send it to your friends instantly. Don't like typing on mobile phone keypads? With Palringo, you can just talk naturally in the form of short voice clips - think of it like a super Walkie-Talkie or a World-Wide-Walkie-Talkie(tm)
There's even more to it! With Palringo International-Walkie-Talkie(tm), you can create and join groups - and exchange text, voice, or photo messages with large communities, regardless of where you happen to be. It's a great way to stay connected while on the go.
