Do iFrames embedded in a page get crawled?

I have an iFrame which prints a page hosted by another company embedded in my page. Their links don't include rel=nofollow attributes, so I don't want Google to see them.

Do spiders crawl the content in iFrames, or do I have to ensure that the links on this page include the nofollow attribute?

I know in the past iframes have not been crawled. Last year at SMX when Matt Cutts talked about pageRank sculpting and using nofollow on internal links, a big discussion emerged afterward. One of the things people suggested was putting your non important internal links (seo wise) in an iframe so search engines wouldn't see them. That was about 9 months ago or so. So at that point I believe search engines could not crawl and index content in an iframe. I haven't yet heard otherwise.

Danny Dover also mentioned in his new book (Search Engine Optimization Secrets) that iframes do not get crawled. Just another source backing up Daniels answer.
