Cannot Specify State in the Mobile Web Interface

In the Mobile version of the Four Square page, I've found that I cannot change the State for new locations I'm adding. The problem is that I live in the Philadelphia area, but on the New Jersey side of the border. So the problem is if I tell Four Square that I've found a new place, and all I have is my BlackBerry, I can't tell it that I'm in New Jersey.

Now, ordinarily this isn't a problem, but it appears the only place in the area on Four Square is the bar, and me and my crowd, while we appreciate the bar as an enjoyable venue, we like diners and other eating establishments too, and not all of them have WiFi (actually, I think only a couple local coffee bars have WiFi), so I can't just use the iPod Touch app.

Can you fix this, please?
