Cellebrite can tranfer contacts from ANY phone to ANY other phone, no matter which brand or carrier. This is a small machine that corporate sprint stores use every day. It can be done, and quite quickly I might add. It uses the infrared on the Treo and the Tour (sprints cable #100). Both must power on and the infrared must work on the treo and the charging port on the Tour. Bluetooth is not needed on either phone. Radioshack, Bestbuy and 3rd party sprint stores might not have it. Calling tech support won't help.
go to
www.sprint.com/storelocator and call the closest store and ask if they can do it or if they have a cellebrite.
Or you can do what Kenward1 suggested and sync through outlook if you have access .
