If you use MobileMe with your Iphone, think twice about syncing the Notes app on MobileMe. For months I didn't and one day I did and all my notes on my Iphone disappeared, never to be seen again. When you sync your notes to MobileMe and there is no place set up to receive them in MobileMe they are removed from your phone and are not replaced on your phone. No warning options, no courtesy messages indicating that you are doing something that cannot be undone. If you sign on to MobileMe and ask to have your Notes synced and then decide you don't want MobileMe anymore they will be removed from your phone. If you sign on to MobileMe and click on to have your Notes synced and then change your mind a minute later and click off to not have your Notes synced anymore on MobileMe but instead decide you want them synced to your computer, you better write them down before you do because you will not be able to do both. Basically, when you create them on your phone, they are stored "in the cloud" and sent back to your phone to view only. When you remove the connection to "the cloud", poof, they are gone forever.
