Question about 503 Series
Sorry if this is covered in another post, but I did a search and could not find it.
Can someone please explain what the 503 series and 603 series comments mean when people are talking about Kindle Paperwhite screens? Where is this information? What do the different numbers mean?
My refurbished Kindle Paperwhite is going to be delivered any minute now. I checked the serial number in my amazon account and it did not have a 503 or a 603 in it. Hopefully the screen will be a good one. . .
