I know in earlier Palm OS versions there was a limit of about 10,000 enties for the address book. I would like to know what the limit is on the current system - using a Treo 600 on Sprint. My friend has a database of 20,000 people he would like to load of the Treo - can it be done? He would buy a treo if it is doable. On his old Palm he hit the limit at some point and it rendered that utility unusable.
