THE ULTIMATE MOBILE SITE PORTAL !
Yourshortcut.mobi is a great site to access all kinds of mobile sites from your Blackberry. News, Sports, Travel, Banking and Weather are just some of the categories you can access.
The neatest thing with this site is you can request for links to be added in three steps. Click the link request, put in your site and send it. You will even receive an email back when your request has been added.
Last count, I believe the site has over 500 mobile sites by category and growing daily.
