The easiest way of transferring Address Book, settings, custom ringtones, etc. between different BB devices is to use Device Switch Wizard of the Desktop Manager (installed on your PC). If you need to transfer Address Book between a BB and a regular phone then it's a bit more complicated, you would need to find a software for this.
SIM cards installed in Telus and Bell Mobility BlackBerries are designed to get the phone working on GSM networks outside North America, as both Telus and Bell Mobility are using CDMA (at least for now, they are trying to switch to GSM, so expect to have more fun later because of this). With most (all?) BlackBerries you can't even transfer you Address Book entries between BB device memory and the SIM card.
