Yes ...we were also positively impacted with latest Google update & our site linksbull.com ..went from PR0 to PR2 for homepage &PR1-2 across other pages..I guess Google is rewarding sites for some good SEO work..I also observed few sites with PR 4-5 that lost there PR & came down to 0 bcoz of back links from bad network of sites...High time for webmasters to build quality links..
Cheers!
