Title: Update Resources/dropbox.js

Consulting the SDK iOS Dropbox, and more specifically the file for DBSession in iOS, I found that in API url is formatted in the format "%@://%@/%@/connect_login?k=%@&s=%@&easl=1%@"
If, therefore, in webview uses this url to log in, you will see the same login page of the iPhone, then no other link :)
