Sign up here: 2012 Xbox Live Update Public Beta (https://connect.microsoft.com/XboxLIVEUpdate)
I'm in - looking forward to testing out Internet Explorer on the Xbox.
Already full...Boo!
Missed out, guess I deserve that for sleeping through the day.
I'm officially "in". I just registered my console tonight.
Downloaded my update this morning. IE is a nice addition.
How long is the beta? Not that I care about using a web browser on my Xbox but some of the other features are interesting.
It's been opened up again: Open Call, More Testers Welcome (http://majornelson.com/2012/08/21/open-call-more-testers-welcome-for-2012-xbox-live-update-public-beta/)
Thanks for the heads up...looks like I'm in.
Cool.
I've gotten a bunch of updates over the past few weeks, but it would be nice if Microsoft actually told us what the updates addressed.
