The mobile (usablenet) version of delta.com hasn't worked in weeks/months. I think it stopped allowing you to sign in coincident with the addition of last name as a login credential on delta.com (the mobile version still uses SM number and PIN only).

Any idea when this will be fixed? It prevents logging in to get an electronic boarding pass on your iPhone/Blackberry. Yes, I know you can bring up your boarding pass using the locator number but who has that handy when they're queuing up at security? Requiring the use of the PNR is a really lame workaround, not a reasonable solution to the fundamental problem of the mobile version of the Web site being out of sync with the main one.

@:-) Even better: a Delta iPhone app just like Avis, Hilton, Starwood Preferred Guest and other travel industry companies have. Not an unreasonable thing for the world's largest airline to provide, is it? And while you're at it, port the same app to the Blackberry, Android phones and Palm Pre. Why is this better than a mobile Web-based app? You can store your login credentials inside the app and never have to key them in again on your phone. Much easier to do while you're walking through the terminal on your way to security.
