Contacts Transfer 1.0 Contacts Transfer freeware greatly simplifies the transfer of contacts, including call groups and pictures, from mobile phone to mobile phone. In order to do this, the free program compresses addresses as much as possible and transfers them through memory cards, Bluetooth, or an infrared connection. Contacts Transfer requires that the free program be installed on both cell phones. For users of Version 1.0 or 2.0 Series 60 cell phones, the file must be installed as "Contact_1_2.sis," while users of Version 3.0 must install it as "Contact_3.sis."
