I was afraid that would be the case. Why? SIM cards can be transferred from phone to phone and all data goes with it. When a phone breaks, data stored only on the phone is lost for good. Maybe you can answer this for me: can I transfer the phonebook off the phone to my computer; and then transfer it from the computer back onto a new phone?
