This may seem like a elementary question but I have never had to worry about it until just recently. My wife just got her first iPhone a few weeks ago and she is wanting me to put some apps on it. When syncing her phone in iTunes, how do I keep from having my contacts, calendars, etc dumped onto her phone? Do I need to set up a different iTunes account for her, different contact list on the computer, different calendar? Again sorry for the basic question but with all of my devices I have just never run across this issue.
