Orphaned Email????
One of my 3G iPhones frequently gets a message "Orphaned" at the top of the screen when going to check Mail. What's up with that???
iPhone 3G, Mac OS X (10.5.1)
Try a reset followed by syncing. Reset by pressing the Home and Sleep buttons until you see the Apple logo, ignoring the slider. Takes 5-15 secs and you won't lose any data or settings.
