I've previously posted this in the iPod touch forum but got no answer, so I figured I'd post it here since this forum gets more traffic and my issue should extend to iPhones as well.
I'd had been having problems with my device's battery, so I took it to the Apple Store to see if they could check the health. At the Apple Store, they ran a diagnostic test on my the device and said nothing was wrong with the hardware, but there was a lot of corrupt data. I had just DFU restored the device about 1-2 hours before bringing it in to the store, so I don't see how this is possible. I had previously jailbroken my device, but, again, I don't see why it would matter as I had just restored. They said that they would do a "deep restore" of my device to get rid of the corrupt data. They also said not to restore from a backup as it might contain corrupt data.
Does anyone know where this corrupt data comes from, how it managed to say on my device after restoring, or what the Apple Store folks could "deep restore" that I can't?
