Just like they promised the folks over at FourSquare promised they have updated at least one of the mobile applications to version 1.7 right before SXSW. So far it looks like the UI has been revamped on this version a significant amount, bringing it more in line with the UI which has been unleashed on the website over the last week. I look forward to seeing the updates of the rest of their apps. If you dig around and find anything extra please let us know!
