An app that automatically updates your phonebook

Tired of keying in the details everytime someone in your contact list changes phone numbers or address? Help is here. "6Degrees", a startup, has developed a self-updating phonebook for your smartphone that verifies and updates contact details on its own. 

Founded by Niranjan Rao, a former Singapore-based investment banker, and Arun Samudrala, a Bangalore-based engineer, 6degrees is like a social network within your phone book. 

"We want to create your own private universe of relationships within your phone," said Rao. "In a few months, we will look for investors who can bring us industry insights as well," he said. 

With this app, users can update their contact details and share it with trusted friends and the friend's phone automatically updates the new number. People will be able to access all connections from across networks in a private manner. 
 6degrees recently bagged a deal from Lava, maker of Xolo handsets, to make 6degrees the default phone book in its mobiles.
