Palringo today announced the addition of vocal instant messaging functionality (push to talk) to its rich messaging iPhone application. This app allows users to use push to talk functions without being locked into a carrier or certain equipment. Other Palringo-supported platforms include BlackBerry, Windows Mobile, Symbian, or Java based devices from manufacturers including Nokia, Motorola, LG, Samsung, HTC, HP, and Sony Ericsson.
Palringo integrates with instant-messaging services such as AIM, Google Talk, Yahoo, Gadu Gadu, ICQ, Jabber, and Windows Live. Users can also use the app to contact their friends using iChat. Palringo is available for free from Apple's App Store.
