How to format my Nokia Mobile?

Want to format your Nokia? I think the reason behind formatting your mobile will be some virus attack. Try to install some antivirus software for mobile. If it doesn't work, you should format your mobile phone. There are two ways through which we can format a mobile. Hard Reset and Soft reset. Soft reset means resetting Nokia by means of giving it a command through keypad. Hard reset means the same but it requires some key combinations simultaneously.
