Hey everyone! My N800 arrived today. It's charging and I can't wait to get started!

I have a question about formatting the SD cards (to completely erase them). Is there a menu function to format the SD cards while they are inserted to the N800 or do they need to be formatted on my PC? If I need to do it on the PC, are there any specifics? Like FAT or FAT32? Can I click "device defaults" and format like that? Any help will be greatly appreciated!
