Register iPhone "Password cannot contain spaces"
I want to register my iPhone but cannot login to my existing Apple ID because the screen shows an error saying my password cannot contain spaces...
However, my actual password does contain space(s), and I have never experienced issues with logging in elsewhere. (appleid.apple.com, iTunes Store, developer.apple.com, ...)
Is this some kind of bug in the register form?
