According to Bing, the redirect should take hold within a few days, not weeks.

One of the more general problems that I regularly see regarding 301s - especially when done on a large scale, is that the major pages get spidered and changed, but this breaks the links to the old urls. If the old urls ONLY had internal links, then a crawler will never get to the page again through meritocricy. You may need to find a way to help it!
