How To Delete iPod Application

I have several applications that I cannot delete (no black x). These include Rock, youtube, stocks, a clock, weather, maps, winterboard, ect. Is there a way I can delete these from my ipod or PC?

Applications which came preinstalled with the iPod’s OS cannot be uninstalled, like Stocks and Youtube.

To delete an application from your iPod, touch the icon, and hold it down till the icons start wobbling. Then hit the little “X” on the corner of the icon to delete. If it is a preinstalled file that is part of the OS, no X will appear.
