Or you can try this 'If it were a S60 Nokia phone (like the E-Series), you could have probably used Google Mobile Sync to copy contacts from the phone to Google Contacts and then use Google Sync on the iPhone again to bring those contacts from the cloud into your phone’s address book.' - Copied HERE
Or copy the contact from E72 to Nano Sim then import to iPhone.
Why don't you try to copy the contacts to your sim card then transfer it to your iphone?
I agree wtih notevenfollowed, why don't you just copy your contacts to your sim?
