How to format and reinstall Symbian S60 smartphone?

[john]

Hello,
my problem is that I have a Nokia X6-00 8GB smartphone for about a year and I have many applications installed. But that old Symbian OS isn't built for bearing such heavy application burden. One great example is that the built-in application uninstaller will broke once you have larger amount of applications installed.
But back to the point. Now when I'm aware of this OS imperfection I want to format whole system and reinstall it. So I can install only few needed applications and have faster experience. Because now is my phone so slow that sometimes I can barely write a sms.
Any help is appreciated.
Thanks

Download MobiShield (free version) from ovi store. There is a application manager, from which you will be able to delete all unnecessary apps.
