I was checking out the iphone 3GS in the apple store and logged into facebook in Safari, not in the app, and forgot the log out (dumb move I know but it just didn't cross my mind at the time as I never do it on my regular iphone 3G) The next day I got some status updates that I know I didn't post. I changed my password on my mac at home and logged out. Would this require the iPhone in the store to log in again? Also, do the people in the apple store reset the iPhones regularly? I was on the iPhone yesterday and the status updates were today.
