I must say, rather live with the Welcome than try all sort of magic. It would seem that the Welcome screen can be changed to Log In -screen, or it can be get rid of by a phone call to xxxxxx-ccccccc-xxxxxx or something, and the latter I do not recommend.
Not being rude, but sometimes you just have to live with things: each time I start my car, I have to look at these half a dozen lights...
