Nokia, the leader in wireless communication is in the news again, but this time, not for good reasons. Last week it was revealed that over 46 million batteries used in the Nokia phones could overheat and the company would replace them for no cost to consumers. Not all the Nokia batteries are found faulty, only those BL-5C batteries (manufactured by Matsushita) had been found to overheat while being charged, and thereafter stopped working. Nokia says there is no need to panic. The wireless major is advertising in the Indian newspapers (the problem is said to be found in India) saying 'Your Nokia Is Safe To Use'.
