I have an iPhone and I am changing companies. I own the phone but the company owns the number, so if the phone is shut down before I can copy contacts can I still retrieve my address book from memory?
Well, you all offer helpful solutions, thanks! And here i'd like to share mine, have a look:
If you are using Windows OS or MAC and also have used to sync your phone with iTunes,then you can see the contacts backup file under the loations listed in the link below -
You can also use iPhone Backup Extractor or CopyTrans Contacts to backup your contacts
In principle, DalSan is right, but to be on the safe side, why don't you back up your contacts as discussed on https://discussions.apple.com/thread/3824602?start=0&tstart=0 !
Have you synced to iCloud? Perhaps you can recover from there
The contacts would be stored either on the internal storage, SIM card, our both. Whether the phone is deactivated from the cell provider's service or not does not matter because it had nothing to do with what is stored internally on the phone. Only the voice and data functions would cease, making your iPhone into an iPod Touch, essentially. I'm not an Apple product user, but I think your contacts should be backed up to your Apple account as well, which cell phone service providers have no control over also. I wouldn't worry unless your contacts are not backed up at all and you factory reset the phone.
