I've been the proud owner of a 7250 for several hours now. Is the "desktop", as it were, properly called the "ribbon"? And regardless of what it's called, is there a way to put a shortcut to an Internet bookmark on it? All help is appreciated...

Nope. Though there is a third party app. I think I recall seeing a mention about it on PinStack.com - Where BlackBerry Professionals Connect!. It might have been discussed here... Have you searched?
