Can't login to WP-Admin from a mobile device

I’ve noticed this since I upgraded to 3.0. In the past, I could go to my wp-admin from a iPhone or Pre and login and make changes to my site. It’s great for when you’re on the road. However, since v2, I now can’t seem to do that. If I touch in the text fields for username and password, I don’t get focus. Nothing happens. It’s a little better in v3.0.1 where focus is immediately achieved in the username field but I still can’t get into my password field and thus, can’t login. Anyone else experiencing this sort of wackiness?
