Whats the best way of tranferring all my phone numbers from my sony erricson c905 to my new iphone 4 ?

Obviously the sim cards change size etc ?

Any ideas ?

Cheers in advance

Is there anything to sync the SE phones contacts with outlook as that would probably be simplest way.

The way I did it was to save all my contacts to the micro SIM (using the adaptor), then pop it in the iPhone and select 'Import SIM Contacts' in Settings > Mail, Contacts, Calendars.

The best method and for future proofing (so next time it is as easy as possible) is to sync your Ericson with Outlook or other app, export the contacts from Outlook to a CSV file, upload that to a gmail or google apps account and then enable google sync on yoru iPhone.

This way all you have to do on yoru iPhone (or any other smart phone that supports active sync) is to enter a username and password and it pulls down all your contacts. Any changes you make on your handset are then added to your contacts on gmail and should you lose or change phone all your contacts are niceley backed up and can be pulled down to you new handset with ease.

You don't need to do that, like most phones you can sync it to your gmail account. Use the syncml instructions on the google sync website.
