Is iPod Jan Software Update tied to one iPod or one Account - No audio

Question

I think I've been a good scout thus far. I've followed the forums, all the complaints and all the issues and STILL purchased the Jan Software update for my iPod 16 GB.
From the advice, I knew to back up my music, make the purchase and do an automatic sync from my mac to the iPod. Apart from a few hiccups this worked fine and the update did appear and I could use the applications.
Unfortunately, post-update, there was no longer any audio output from the audio (headphone) jack despite trying multiple headphones and trying to play music, podcasts or video. When I connected my iPod Touch to the iBook, the iBook could play media from the iPod with audio through the iBook's speakers so I knew there was audio.
Apart from the fact that this is highly irritating, I decided to take the iPod in today to a service centre who told me they would look at it and only contact me within 3 -5 days. I would probably get a new iPod if they couldn't fix my problem.
When I told them that my iPod had the knew update they told me that they couldn't/didn't know anything about this - and didn't know what new iPod would be exchanged or which software.
HERE'S MY QUESTION - in the event that I do get a new iPod Touch without the update or with a version lower than 1.1.13, will I be able to use my purchased Jan Software Update or do I have to re-purchase?
Thanks.

The iPod touch January Software Upgrade can only be synced to iPod touch from the primary iTunes library. If the user is manually managing music and video on iPod, this is the computer where they first set up the iPod or first set it up after restoring the iPod. The "iPod touch App Pack 4A93.ipa" file can be copied from the computer where you purchased it to your primary iTunes library computer, and sync the iPod from there.
The file is located here:
Mac OS X:
~/Library/iTunes/Mobile Applications
Windows XP
C:\Documents and Settings\[user name]\Application Data\Apple Computer\iTunes\Mobile Applications\
Windows Vista:
C:\Users\[user name]\AppData\Roaming\\Apple Computer\iTunes\Mobile Applications\
Note: These locations are hidden by default in Windows. You can these locations by choosing "Show hidden files and folder" in the View tab of the Folder Options Control Panel.
Once you have copied the "iPod touch App Pack 4A93.ipa" file to the computer with your home library, make a new folder named Mobile Applications in the correct location, and place the "iPod touch App Pack 4A93.ipa" file there. Open iTunes and sync your iPod touch.
