The download version of the Windows Phone 7 Training Kit has been updated for the recent Beta release of the WIndows Phone Developer Tools. I think the online version may still reflect the April Refresh version. Expect it to be updated shortly. Meantime, you can download the updated version here or go to the training kit home page and click the "Download Training Kit" link in the top right-hand corner.
Microsoft Switzerland have created their own hands-on lab (in English) which I'm just working my way through at the moment. It's based around creating a Newsreader application with Silverlight and includes concepts like the panorama-style UI that features in the WP7 hubs. Well worth a look (although AFAIK this has not been updated for the Beta release). Read the blog post or download the lab.
And of course, don't forget the Jump Start training taking place on 20th/22nd July. The timings are a bit awkward if your in Europe but I'm sure it'll be worth staying up for it. Click here for more details or to register.
