Probably the single most frequently-asked question of our editors here at i Lounge is “How do I copy music from my i Pod back to my computer?
The problem is that when one attempts to restore an i Phone, all the data stored in the phone's memory, regardless of whether they are important or insignificant, will be wiped out and wouldn't be back once the phone boots after the restoration.
Go ahead and authorize i Tunes with the new computer as well.
To put it simply, because data is meant to go from the computer to the i Phone, not from the i Phone to a computer with i Tunes.
All of this is made a bit better for i Cloud users, but you will still need these directories copied over before you can use Wi-Fi sync and sync flawlessly to a new machine without losing data.
Frankly, it’s often faster to just download the update files directly from Apple since they are delivered through a CDN they tend to go at or near your maximum download speeds.
All software programs, i Tunes included, are vulnerable to becoming corrupted.
