Trying to fix what appears now to be a hardware problem with my iPhone 4, I decided last night to restore 4.2.1. Not wanting to go thru the hassle of restoring all of my JB apps and settings manually, like I've always done, I decided to bite the bullet and bought Pkgbackup. Backup to Dropbox was much quicker than I expected Anyways, the way I did my restore, I installed 4.2.1 and JB with GP. Then synced to iTunes, setup from backup (rather than as new). I let it sync my contacts, cal, email, and apps, then stopped it when it started syncing my music. Then installed Pkgbackup from Cydia. Went in and selected everything except the iphone ios files it de-selected, and let it restore. Went really well. Except that my prefs and Springboard layouts were still screwed up. Restored prefs and SB again. No luck. SSH'd in and noticed that all of those files restored by Pkgbackup were showing as Root:Mobile rather than Mobile:Mobile. A quick chown and a respring and all was good again. Is there a bug that caused it to restore with the wrong ownership permissions, or did something just go wacky this time?
