How do i join other servers in Minecraft PS3?

To join other servers in minecraft on PS3, you need to first ensure that you have a PlayStation Network account and are connected to the internet. Unfortunately, Minecraft PS3 edition does not support online servers like the PC version; it only allows for local multiplayer or private games with friends. You can join games hosted by friends in your PlayStation Network friends list by selecting "Play Game" and then choosing their world if they are online. For online experiences, consider upgrading to a newer console version that supports server features.
