my friend was “patching” his iPod touch up to 1.1.2 the other day. He had failed to patch correctly and had upgraded to 1.1.2 and lost, the nice enhacements to 1.1.1 that he had installed. So the procedure is to rollback to 1.1.1. However he was running on the mac and the latest version of iTunes was installed. When he selected the 1.1.1 ipod touch flash image iTunes promptly notified him of an error and deleted the 1.1.1 firmware off the disk, which was a bit rude. From this I guess iTunes now checks the firmware’s crc to see if it is the version with the tiff vulnerabillity in as I heard rumours they have patched the 1.1.1 firmware. So take a leaf grab the 1.1.1, 1.1.2 firmwares and an old copy of iTunes and archive as soon as possible.
