Unfortunately at this time, even if Apple did grant you a voulcher for the purchase of the 'January Software Upgrade' so that you can obtain the package for free,
you physically cannot buy it.
The Janurary Software Upgrade has been completely pulled from distribution on iTunes in light of the new 2.0 software upgrade coming to iPod touch and
iPhone on July 11th 2008.
The January Software Upgrade is no longer available to devices which don't have it pre-installed at purchase. Model numbers ending in /B have the upgrade
pre-installed. Models ending in /A do not. You will find the model number of your iPod touch on your dispatch e-mail from Apple.com
I suggest you Contact Apple and ask them to swap it out for a /B model.
