It is possible to transfer the lists from one device to another. Please note that this will overwrite any list on the second device. After the transfer the 2 devices will contain identical lists.
If your lists use Contacts (as opposed to manually typed in data), then both devices will have to share the same contacts.
To do this transfer, use is made of the dropbox backup/restore. The idea is to do a backup from one device, and then a restore to the second device.
