Although it might not be the best idea to take a jailbroken device to the retail store, it might be worth a shot.
FWIW, I just used Spirit to jailbreak my iPod touch 3G 3.1.3 (which is really 2G hardware). I had used Blackra1n before but that was a tethered jb.
This is untethered and works fine. So nice to not have to worry about powering it down when I'm away from my laptop.
