A:Answer It's not an older version. The 935f is the international version still being sold in Europe. While Snapdragon is marginally faster it also heats up more and is not as energy efficient. Yes the935u supports CDMA but is that worth the one to $200 difference? Additionally, the U, which is the North American version, can be placed under warranty while Samsung does not support the international version with the warranty. I still feel like I must be missing something?
