Check the Sony Stores , they have older version on most stores as of July 16, 2006 . Click and a popup will appear, click on stores on the bottom left will show a map where you can locate sony stores at the mall.,etc


If you are not sure ask sales for firmware 1.5-2.00, they will let you open up the box to confirm although this against policy they know you will return it if not correct firmware. Sony Stores have excellent return policy.

I check 6 sony stores, 5 stores still have A version 1.5 firmmare, the other one had B firmware 1.51 I believe

Where do you get your serial from? Is it the numbers inside the UMD slot, or is it on the box somewhere?

on the box theres a sticker with 3 barcodes on it under the 120V theres a letter all by itself thats the one u go by

Ah thanks. Mine says 240V but i'm guessing that it's still the same. Mine appears to be the G Firmware.
It's been put up to 2.6 which looks like i can downgrade.
