In short -- no. If you have your heart set on modding Skyrim you should just buy the PC version, which can be found on sale for ~$35 with all DLC if you go for the Legendary edition. There's honestly a lot of misinformation in this thread. You can't mod Skyrim on your PS3 in a similar manner to the PC without jail-breaking it (which you don't want to ever do), and even if you did, you open both your game saves and PS3 to a myriad of unsolvable issues. It's not even close to worth it for mods that likely won't work anyway. Now, what people have been discussing in this thread is a bit different. Some people download "modded" Skyrim save files from the internet and just add them to their PS3 with a USB stick. All that these generally consist of are a few additional sets of armor/weapons already in the game. You have no ability to actually "mod" anything yourself, it's like what would happen if you saved your Skyrim file to a USB stick and traded with a friend for theirs. If you want to have control over what the file contains you would need Skyrim on the PC anyway: people take a PS3 save, convert it to PC, edit it, and then convert it back. During these conversions there are a lot of opportunities for screw-ups that waste the whole process. tl;dr buy the PC version if you want mods. Any claimed alternative methods for consoles are a waste of time or complete BS.
