You can now sign up for a Windows Live ID (the account, formerly called a Passport, that lets you use Live services like Hotmail) from your mobile device, bypassing the need to use a computer to do it. That means that if users try to use a Live service from their phone and don’t have a Live ID, there won’t be the annoying barrier of having to wait to get home to actually sign up.
To do so, go to mid.live.com/reg, or just try to use a Live service and click “Get a Windows Live ID”. I just used it to create “firstname.lastname@example.org”*, and its a two step process. Just enter a Live ID on page one and (assuming its available) enter a password, birth year and four-letter captcha on page two, and you’re done. It’s so much easier on the phone than the computer, you might want to use this method every time!
* – Tell me you got the reference! Jeez, read this.
