Yes there is. Swiping from the top activates an overpanel on both iOs and Android (I don't know about Blackberry). However, I don't think this is what you're looking for. The obvious reason against implementing it this way, is that it will conflict with the native behavior of your phone. Besides, how would the user know from where to swipe to trigger the overpanel and how does the user know what's in the panel? So what are other ways to solve this?
Country selection is always a bit difficult. There are a lot of countries and the language in which to show them is not as straight forward as one might hope (eg The Netherlands, Nederland, Pays-Bas).
First of all, let's make it clear that the country can be changed. This can be accomplished by showing 'change country' next to the country, or putting the country in a pull down / select box. I'm sure there are other ways, but these are the most common.
But how to solve the sorting problem (the United States would be be at the end of the list while, in most cases, it's the most popular choice)? You could use a grouped pull down and start with the three most picked countries and then start the alphabetic list.
