I wanted to know if someone had a method that could be used to move a
list item from one folder location to another within the same list
(e.g. to a sibling folder) in MOSS 2007 using the SharePoint/MOSS
Object Model and retain the same ItemID. The list item has no
attachments or anything like that.

Example:

Here is the original structure...
List 1
Folder 1
Item A
Folder 2
List 2

I need to move Item A to Folder 2
List 1
Folder 1
Folder 2
Item A
List 2
