  1. #1
    Default iPhone 3G downgrading. A simple question
    Right now I'm using iPhone 3G with 4.2.1 firmware and I wanna downgrade it to 3.1.3 but i don't want to flush away all my text messages, so is there any way I can downgrade and save my text messages?
    Thanks in advance!

    Yes, use any third party software on your computer to backup your sms, not itunes.

    Copy this whole directory structure ( /private/var/mobile/Library/SMS ) to your computer (WinSCP/ssh/etc). Make careful notes about the current ownership (user mobile) and permissions (generally 644 for files and 700 for directories) of each file and directory inside.

    After restoring to 3.1.2/3, set up your phone as new, then replace the contents of the current (and empty) /private/var/mobile/Library/SMS with your backup and set the ownership and permissions of all copied file and directories. Reboot.

    Note: I have successfully used this procedure for Contacts (AddressBook), Calendar, and Notes and to some extent WebClips (SpringBoard internet web links)

    And I can't understand what you are trying to say about the permissions thing in paragraph one. Please explain it in a simpler way. Thanks

    I think Pkgbackup will backup your sms as well, after your backup , remember to sync with itunes first, your backup will be stored in contacts. Syhc your contacts after your restore > install pkgbackup and do your restore again from backup

    PkgBackup works great. I use it

    I also do manual backups as I mentioned before for safety .... but PkgBackup is good, automatic, and doesn't require any unix knowledge.

    Does pkgbackup require restoring from backup? Just curious as I've never used it and aptbackup requires it, bc iOS 4 backups won't load onto 3.x. If not then all systems go

    Pkgbackup is a paid app is there anything available for free?

    And ill be downgrading the firmware of my iPhone so if I'll copy the files from that directory and paste it after the downgrade, so it won't cause any kind of problem? Are you sure of this thing?

    After the downgrade I think I have to setup my phone as a new iPhone, I can't restore it From backup and I have the backup of my contacts in my email account.

    Sure you can, If you are using pkgbackup, install pkgbackup , select view restore > refresh it > select restore.

    Unfortunately, it is not free, I bought pkgbackup awhile ago and it was like only 2.99, now i think the price has gone up.

    But it does install back most of the stuffs.
