Why not try the give away first you never know you might win http://www.xpgamesaves.com/topic/43587-xbox-live-update-public-beta-key-giveaway/
I thought beta updates were console specific and locked with a seial number too. you can update but your live connection wont work till the official update comes out if you use another unofficial method
Shouldn't be mate, on the last beta update a few members on here gave away there keys including me and the winners all seemed to be ok when downloading it etc
