Does that sound likely?
I would guess that no ads version would usually have older firmware because they sell slower. If they are in stock but take longer to deliver, I think that would be because they are in a warehouse farther away. If they are longer to deliver because out of stock, I think that increases the chance of getting newer firmware.

I can also check the date of manufacture from the serial number I guess, when it is paired to my account, and before it is delivered. Aggh.

I'm updating my son's PW now and I can't believe how easy this is compared to previous jailbreaks.

Updated to add: Or maybe certified refurbished kindles are less likely to have the most up-to-date software?
In my limited experience, refurbished kindles have older firmware.
