With the ever changing technology, a new application for smartphone owners has gained ground. It’s known as WhatsApp.
The WhatsApp Messenger is a proprietary cross-platform mobile messaging app for smartphones allowing users to exchange messages without having to pay for SMS.
The new application is available for iPhone, BlackBerry, Android and Nokia and those phones can all message each other! Because WhatsApp Messenger uses the same internet data plan that used for email and web browsing, there is no cost to message and stay in touch with friends.
In addition to basic messaging iPhone, Android, Nokia and BlackBerry WhatsApp Messenger users can send each other unlimited images, video and audio media messages.
The application synchronizes with the phone’s contact’s book, so users do not need to add contacts in a separate book. As the underlying technology the application uses the open standard XMPP.
WhatsApp was founded by two guys who spent combined 20 years doing geeky stuff at Yahoo! Inc. before starting WhatsApp Inc.
SMS is an older messaging system with a limited functionality and high cost.
WhatsApp Messenger aims to provide more at a lower cost. We are sure you and your friends will figure out the difference between SMS and WhatsApp Messenger very quickly.
However, security concerns arose in May 2011 when a security hole was reported in WhatsApp which left user accounts open for hijacking.
Communications made by this previous version of WhatsApp were not themselves encrypted, and data was sent and received in plaintext, meaning messages could be easily read if packets could be sniffed.
In September 2011 a new version of the WhatsApp Messenger application for iPhones was released.
However, 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.
