You can store name & numbers on the SIM, but I wouldn't recommend it.
If you've got the contacts on the laptop then you just need to sync the new phone w/your computer.
If not, then you can:
-> Beam all the contacts from phone to phone.
(There is a beam category[all] option)
-> Backup to a SD card and restore to the new phone w/that SD card.
-> Manually put in the info from phone to phone.
Hope that helps.
Oh, btw, the contact information is not stored on the SD card, it's stored on the Treo's internal memory.
