Latest Google PageRank update was on April 3rd 2010, that is 2 days back. I wanted to check out the PR of all my subpages as well. However, I was too lazy to check one by one. I had 2 solutions for this. Either make a PHP-curl script and put all the links in a loop or find a tool which just did that.
I just googled and found http://pagerank.bthomson.com/
You can check PR for multiple links or all outbound links from a page.
