Re: How to format Nokia 5310
As you have said that your phone takes a long time to operate, this seems that there is a huge load on your phone memory. Try to install nokia pc suite , now connect your phone through cable and select pc suite mode. Now,go to your phone memory and open themes folder, delete or transfer all the themes and you will get ur memory and your mobile's performance back. It really works, check it out.! If then also it doesn't work, the last option is format.
