Has anyone experienced that the 4g ipods are uploading slower than the 3g ones. I just bought a 20gb 4g ipod and it took like 15 minutes to upload about 1500 songs using a firewire cable and then those same 1500 took only like a minute to upload on my friend's 3g ipod using the same firewire cable. is this happening only to me or is this the way it is with the new 4g ipods?? :confused:
