Bloggers and Webmaster's Grumble on bing PR

It appeared utmost surprise to me when I learnt that bing.com has already obtained Google PageRank 2 on the second day of its launch. How could it be? It is almost impossible to be indexed in this short span of time!

Web Page URL:	http://www.bing.com
The Page Rank:	2/10
(the page rank value is 2 from 10 possible points)

You can check on your google toolbar when you open bing.com.

The question here is not whether bing.com worth PR 2 or not. The question is can google adapt two different criteria for different domain names? What are the criteria based on that google awarded bing.com a PR 2 in two days of its launch, Google must clarify. There has spread a great disappointment among bloggers and site owners who struggled hard to improve on PR. Since PR directly effects the SERP its always valued by webmasters.

Microsoft launched new search engine bing.com on 28th, After that Google didn't update PR, is google specially update any particular site for PR? It had PR 0 on 28th and 2 on 2nd June!
