Having recently bought a new iPhone, I'm trying to sell my old model, but in order to do so I first want to erase all my old data from my phone. I have a few questions around this, and I'd be grateful if anyone could help me with the following:
1) In order to take my old phone back to factory settings, do I have to take the sim out of my new phone and put in back into the old one to do the job? is there any way I can reset to factory settings without the use of sim?
2) If the answer to the above is 'yes' (I need to use the sim) how can I be sure that the data on my new phone will be unthreatened by the deletion of the old ie If I am unable to back up all the data from the old phone, will it also be deleted from the new?
3) Assuming I am happy that no essential data will be lost, do I just delete everything in 'Settings' and then leave it at that, or is there something else I have to do after that?
Regards and thanks
Graham
