Did I find some unlocked Barton 2500s?

I called and the guy read me off the STEPPING CODE and it was AQ?? 0331 M???. From what I've gathered all I'm worried about is the 0331. Correct? If this is in fact right, they have 9 of them and I'm thinking about buying 3 or 4 of them at their $95 tariff.

Thanks!

yep week 31 of '03 were still unlocked. so if you wanna get some unlocked bartons get them b4 they run out
