Hello, i'm trying to reload os2008. I want to start from scratch due to some problems i'm having with a few applications. Plus i'm sure i've gathered one too many applications and they have left remnants. I'm attempting to use the Nokia Software Updater and it instructs me to hold the "Swap Key" then power the unit on once its connected through USB. I can't seem to find anything in the documentation that states where exactly the swap key is. I have a Nokia N810. Thanks in advance!
