I have an unopened CECH-2501A 160GB model PS3, but just looking at the box, I'm not sure how to tell if this model is from 2010 or 2011. I originally bought it ~10 years ago with the intent of hacking it, but if the PS3 is from 2011, I'd like to leave it unopened and sell it. The serial number sticker has a UC2 on it, but I can't tell how that relates to the date codes. Any help would be appreciated.
