I have an Iphone 4s running 6.1.2 and its jailbroken. It has been running fine since since 6.1.2 came out and jailbroken with Evasi0n. I noticed that 6.1.3 is out and I thought I would upgrade. So I thought I would run PKGBackup to take a backup before I did the upgrade. I'm running PKGBackup v5.3.4 and when I click on Backup I'm back to the my Desktop. No errors nothing. I did a re-install just in case but still the same. I had this problem when I was running ios 5.0.6 but a re-install seemed to fix it but it doesn't this time. Anyone have/seen this? Know of a cure/solution? I have tried to use different backup locations like Addressbook, which worked fine before and SkyDrive which I used for my last backup when I upgraded from 6.1.1 to 6.1.2.
