You mean recommended websites for viewing on BlackBerry?
Here are some of my favourites:
www.google.com - For searching
www.mapquest.com/pda - The cellphone version of Mapquest
news.google.com - One of my favourite news pages
mobile.blackberry.com - A great little portal, includes weather
wap.oa.yahoo.com - WAP version of Yahoo
www.imdb.com - For movie lookups. Use this while renting movies to verify if a movie is good before renting/buying
NOTE: I edited your topic title to be more relevant!
