I am having a weird issue with the Notes field in the Address book on my iMac and my iPhone as well. I had used a Palm product for a long time and i just recently bought an iPhone. All of my contacts from my Palm treo were ported over to my iPhone and then when i synced with my imac those contacts were added to the Address Book on the imac. Ok here is the issue, on the "Palm" there were "custom" fields and a "note" field, all of the information there was dumped into the Note: field in Address Book. Along with each entry in the note section there is a some additional text (X-Palm-Custom 1 ), i am trying to remove this additional text and each time i try it just comes back. I have tried on the iPhone and then Sync to iMac and on the iMac and sync back to iPhone, but no luck it just comes back.
