Trophies do not go anywhere. When PSN comes back up it will update your records with all the trophies you earned while the network has been shutdown. It can do that because the trophies are part of your records in your harddrive
A man that's addictied to PSN Trophies
PSN is an abbreviation for PlayStation Network, an online network for PlayStation consoles.it is free and you can compete for trophies
Your trophies are recorded on your PSN profile, which you will log into on both your PS3 and your PSVita. On the PSVita you've got the option to just see the local trophies, the PSVita ones, but also the option to check your PSN account, which will show your PS3 trophies too.
They can see your trophies for sure
You cannot. They prevent you from doing this in order to prevent cheating.
Your trophies are sync'd to your online profile, but the only way to store save data online via the PSN is to be a PlayStation Plus member.
To check your trophies on PS3 go to Games in the XMB. Near the top of the list there will be a trophies option, select this and submit. If you have an online account your trophies will be synced to or from your account. After the sync(if any) you will be able to see all your games that support trophies, and the trophies you have earned for each one.
Some trophies are stored locally, for example if you're using a PSVita, it has its own local trophy section. Whenever you've got an internet connection, it will sync your local ones with your PSN ones.
If your Playstation 3 is connected to the internet the Trophy information is updated. This happens automatically and Sony indicated that when the PSN was down (After April Hacking shutdown) that even trophies earned in offline play during the shutdown would be posted after PSN was brought back up. If you are not connected to the internet you may find that you have earned more trophies when you are connected. Trophies allow other users to see how advanced you are and you do not have the ability to update delete or remove them
What Trophies? There Was None!
