2 iPod Touches, 2 Accts, 2 Computers, 2 Generations..Update from 1 Acct?

Question

I have read all the postings on updating multiple iPod Touches but I'm still not sure of what I need to do in my case. I own 2 iPod Touches. I use the newer one (Gen2) for personal use and use the older one (Gen1) for work. I manage the newer one using my personal iTunes acct. on this computer (a Mac Mini), and the other one using a 2nd acct on the PowerMac in my studio. I just updated the newer one on this computer.
Can I update the older Gen1 Touch from my personal iTunes account and not the 2nd account with which it is normally managed? If so, how do I do it and what computer should I use? Ideally I'd like to get the 2nd update at no additional charge, but I would be willing to pay if needed. But I'd like the payment to come out of the money that I already have in my personal iTunes account and not have to add more money to my 2nd account.
Thanks in advance for your help.

Answer 1

Are you saying you have two iTunes accounts but they are both yours? Has that been a pain being able to play your own purchased music?
I wrote that other post about the 4 iPods. I could be wrong but I think you will have to pay twice. You could always sign in to your account with the credit and do both, but you probably should make sure both iPods are also signed in to the same account first, then you may be able to switch back. Either all will be fine or you might have to restore or reload that second iPod. The only reason I even suggest this though is because they are both your iPods.
