Checked my local Best Buy, all of the units there were week 26 and 27. (YMMV obviously on this one). Now I havent seen any info on exactly when they switch over and use the latest firmware in production. But if someone wanted to be really safe. Just check the SN first and make sure its older than whenever 5.14.3 came out.

I checked on ebay, and there's plenty that you can find that are old enough production you can get one that is jailbreak-able out of the box. Also different regions and retailers will obviously have different stock options than what is local for me.

It's posted in another thread here, but when checking serial numbers, you want to check the 9th-12th digits. 9th digit is year (1 or 2 for 2021 and 2022), 10th and 11th are the week it was made (01-52), and the 12th digit is the day of the week (0-7). For the weeks, anything made before 2022 week 16 should be good to go.

The other option, as others have said, is to wait for a new jb which might, or might not happen.
This could be very useful since I want to buy a new one from my neighbor but it has on the back of the box: DSN G001PX1123620H9L. It can't be made in 2023, week 62, so how do I interpret this DSN? The Kindle is sealed, so I can't turn it on to see what firmware it has.
