When you plan to sell your phone, you never who will get it and what he will do with it. Therefore, you need to deleted everything on your iPhone before selling it, for the sake of your privacy.
How to delete your iPhone data for selling
Backup your old iPhone first: Before deleting your old iPhone data, make sure that you've backed up the data that you still want to keep, because the deletion you're going to perform is permanent. No one can recover any data from it with any recovery software. Only in this way can your privacy be protected safely. You can use iTunes or iCloud to backup the data on your old iPhone, or directly transfer it to your new phone with a certain data transfer tool like Wondershare MobileGo for iOS (if you still choose a new iPhone) or Wondershare MobileGo for Android (if your phone is an Android one).
Delete data on the iPhone for selling: Now, you can start deleting all data on your old iPhone. To ensure that the deleted data cannot be recovered by any data recovery software, you need to choose a reliable tool which can finish this work perfectly and won't remember any data by itself. There are a few iPhone data eraser apps on the market, but almost all of them can't wipe the data completely. They can only clean the data under their own directory. The most secure way is using PC-end software. It always can do the cleaning work better. Here my recommendation is Wondershare SafeEraser for iOS. This software can smash everything on the iPhone, and even the government recovery facility can't retrieve anything on it. It's totally safe and easy to use.
