Precautions for Apple 6 use:
1, don't worry about unpacking after you get it. There is an IMEI number on the back of the box. Check whether the machine has been activated first (Baidu Apple will do). If it is not activated, it is best. If it is an emergency activation, it will be normal in a few days. If you use the manufacturer's apple id to activate, you must log out of icloud and log in with your own id, otherwise you need to ask the manufacturer for a password for future upgrades.
And log in to icloud with your id and open "Find My iPhone", so others can't brush their iPhone and can't activate it after brushing.
2.iTunes must be installed on the computer. This software is a backup and must be used to restore the firmware.
3. To register an account (email) on iTunes, you must clearly fill in and remember the password. Every iPhone must be activated through an account. Everything in the phone will be bound to the account in the future, so be sure to remember it clearly, including secret protection. If you want to buy an application, you need to help a credit card account.
