Hopefully you've downloaded The Open app by now, but if not here is the U.S. link at iTunes. I'm not entirely sure what's available in the States, but as I lay out in this Loop item, the R&A has broken new ground in the march toward a 21st Century fan experience with (working!) WiFi throughout the property.
Combine that with the ability to sit in the grandstand and listen to the BBC Radio feed or watch the BBC TV feed, and even get special information pushed to your phone if sitting on the third hole grandstand thanks to iBeacons.
The app it is one of the best-designed I've seen (especially the iPad version) and should serve as the new standard-bearer for golf's other tours and governing bodies to study.
