India running out of numbers?

In an article on ZDNET, it has been reported that India will run out of mobile numbers this year. What does this mean? Besides the obvious that the country will be depleted of available numbers, this illustrates the growth of mobile. What once was accomplished only through personal computers, people now can do with mobile handsets. People also have the need to be connected all the time, whether it be with work or family. It will be interesting to see if the move to a 12 digit phone number system will help, or if it will cause severe headaches as the infrastructure is reset to accommodate the changes.
