I was able to copy my entire address book from Sony Clie to p910a using infared. Turn p910 infared on. Then go to address book in PalmPilot. Click on 'Address' in toolbar at top of Address book page. One option should be 'Beam Category'. This will beam whatever category you are in to the p910a. If you are in the 'All' category, this will beam the entire adressbook to the 'Unfiled' file in p910's 'Contacts' file. If you have lots of entries and several categories in your Palm, it is wise to set same categories up in p910a and beam categories one at a time, transfering each category from 'Unfiled' to appropriate file after beaming. I had 410 entries in 8 categories and this condensed hours of work into about 12 minutes.By selecting any individual contact in Palm address book and clicking 'Beam Address', entrees can be sent one at a time but of course this is not appropriate with 410 entrees. While beaming a large category, the screen on my p910 went kind of haywire but I just left all alone and it worked! Good luck!!
