What's App(Instant Messenger)

Works On:Windows Phones,Ios,Blackberry,Symbian

What's App is not available for Java Phones

WhatsApp Messenger is a proprietary, cross-platform instant messaging application for smartphones. In addition to basic messaging WhatsApp Messenger users can send each other images, video and audio media messages.

WhatsApp Messenger is available for iPhone, BlackBerry,Android, Symbian and Windows Phone only. WhatsApp synchronizes with the phone's contact's book, so users do not need to add contacts in a separate book.[citation needed]

Users must buy WhatsApp if they wish to use it in iOS - 0,79€ in Europe, 69p in the UK store, and US $0.99 everywhere else. For all other platforms users must pay US $1.99 yearly with the first year being free.

The name WhatsApp is a pun of the popular phrase "What's up?"

In May 2011 there was a security hole reported in WhatsApp which left user accounts open for hijacking.

Communications made by WhatsApp are not themselves encrypted, data is sent and received in plaintext, meaning messages can be easily read if packets can be sniffed.

In September 2011 a new version of the WhatsApp Messenger application for iPhones was released. In this new version, the developer has closed a number of critical security holes that allowed forged messages to be sent and messages from any WhatsApp user to be read.
