1) Nokia contacts can be copied between different phones as vCard (.vcf files) via PC Suite
2) or you can do a backup of the contacts from the 1st phone and restore the backuped file to the 2nd phone.
You can use the phone book organizer of nokia pc suite or you may just open it from the "nokia phone browser" folder in your "My computer". you can either do it yourself by copying each and every contacts(through nokia phone browser) you have frm your phone memory and store 'em in a folder in your pc or you could use the back-up facility of pc suite. bluetooth and infrared also works but it will take hours for you to finish... hope i helped
btw. you have got to have a good version of nokia pc suite cause the newest release confuses me... and nokia phone browser is an automatic add-on of pc suite so you will still need the program...
