I got a 4S a few months ago, and when I first turned it on (during personal setup in the Apple store), it walked me through a setup for iCloud, Internet access, Apple ID, email, etc. My sister recently got an iPhone 4, but this setup did not take place upon first boot. She had to configure everything manually, including iCloud. Does this mean her phone was used, or is this feature only available for the 4S and not the 4?
