Can I use itunes to back up my iphone after jailbreak?

Of course you can. Genuine software can be backed up or restored from backup; Plug-ins must be reloaded after jailbreak; The cracked software can be recovered after the system jailbreaks.

To be on the safe side, it is best to use other third-party tools such as iTools to back up important personal data such as address books, short messages, photos and memos.

The choice of backup during recovery is of course determined according to the generation time of backup.
