Note replaced after installing iOS 6.1 and synchronizing with iTunes

you restored your phone with an old backup, with old notes. the only way you are going to get them back is if you restore again with the most recent update that contained the notes you are looking for. if you didnt back up right before you wiped/restored, then you are out of luck.

this is why i wont back up to the computer. many days can go between backups, which leads to things like this. icloud keeps them backed up in realtime and up to date, everyday.

Thanks for your answer,

When you sync with the pc doesn't it make a bkp before? Why does the file on the pc overwrite the newest one on the iPhone?

When you upgrade from ios 6 to 6.1 no bkp is made on the iPhone?

when you sync, it does just that. i believe you need to select the backup option in order to do a back up. separate things. when you restored, it restored from on of your old backups. you should have backed up first, then upgraded the OS, then restored from that new backup.
