I'm wondering if this is a reliable way to backup my jailbroken iphone 3g (blackra1n). Thanks.
1) Use Pkgbackup from cydia to save your cydia packages, then sync with iTunes (Pkgbackup backs up yur cydia packages list to a contact on your iPhone)
2) Use Chronus from cydia to back up app store (and stock) apps with user data then ssh the contents of /var/mobile/Library/Peferences/Timcapsule to your hard drive
3) Restore to 3.0.1 (set up as new)
4) Re-jailbreak with Redsn0w and the 3.0 ipsw
5) Sync with iTunes
6) Download Chronus and Pkgbackup and openSSH from cydia
7) SSH (or use iPhoneBrowser or Diskaid) the Chronus files you moved to your hard drive back to /var/mobile/Library/Peferences/Timcapsule and restore them with Chronus
8) Run Pkgbackup and restore your cydia packages
9) Reboot phone
10) Apply any other settings that were erased during the restore.
This process has taken my restore/re-jailbreak time from a few hours to around 1/2 to 1 hour and you are starting with a fresh restore of the iPhone OS.
I just copied and pasted this from a post I made elsewhere, between step 3 and 4...take it to apple
