Twitter Authorize-App "Don't Have a Twitter account" misdirection when using Mobile Safari

URL Redirection bug on Mobile Safari

If you attempt to authorize an app to access your Twitter account using a Mobile Safari user-agent and arrive at the "Allow" / "Deny" screen while not currently logged in at Twitter, you are presented with a link that says "Don't have a Twitter account? Sign up Now!" .  This link forwards you to:

http://api.twitter.com/account/new?oauth_token=<the-oauth-token-for-the-session>

which subsequently forwards you to:

http://mobile.twitter.com/account/new

which then forwards you to:

http://mobile.twitter.com/account

which finally forwards you to:

http://mobile.twitter.com/suspended.html

If you click on the equivalent link when not sending a Mobile Safari user-agent (in my case, Safari 5.01) , you successfully arrive at a sign up page:

https://api.twitter.com/account/new?oauth_token=<the session oauth token>


In this case I'd presume that the api.twitter.com service is incorrectly forwarding a non-api request ( for the user sign up page ) for a mobile browser over to the mobile domain, but in this particular case should be presenting the user with a signup form hosted from api.twitter.com.  I am only armchair debugging tho.

Incidentally, the sign-in on support.twitter.com is also not working.

Legit. I'll file a ticket.
