Hey I've got an N900 that I've tinkered with over the months and I feel like I've done enough reckless things to "dirty" up the kernel.. or firmware.. or something. I'm not computer illiterate but I'm no programmer.

Anyway, is there a way to completely renew my N900 as far as software is concerned? I've already formatted my SD card and backed up my contacts and I want to make the N900 as if I have just opened the box with none of my old files or anything.

Basically I want to reinstall the OS as you would do on a windows machine.

How do I go about doing this?
