Easy Way to Get New Smackdown Arena
I found this out by myself and it really works! It's pretty hard to eliminate 17 people in slobber knocker mode to unlock the new smackdown arena with the rock so try this! Go to create mode then go to create a superstar then go to moves. Then pick The Rock and it should take you to the moves list then go to running. Then pick attack.When your in attack change The Rock Clothesline and The Rock Forearm Smash to clothesline which is under powerful. Then when your in the slobberknocker match with The Rock trying to get the new smackdown arena just do that clothesline a couple of times to your opponent in the ring and pin.Then repeat this process until you have beaten 17 people. And don't worry you can turn the moves back to default when your done if you want.

Easy Royal Rumble Win
I know how to easily win the Royal Rumble on WWF Smackdown 3: JBI. This may sound stupid but my dad has won at least 6 times with this strategy and he isn't even that good. All you have to do is stand in a corner. The lower Left one works the best because the wrestlers rarely end up there. If you should just happen to walk your way just punch or kick him away and the wrestler should stay way from you unless you and the wrestler are the only two left and your waiting for another wrestler to some down the ramp or you are the last two left. If more than one wrestler come your way than just move to a different corner, going counter clockwise works well. When you are the last one left just sneak up behind the wrestler and knock him or her over. They should hopefully be doing their taunt which will give you enough time to knock him or her over the top rope.

The Betrayal
Accept the tag team title opportunity from Vince, find a partner, and win your first match. Then say that you want to find someone for the 3 man tag team match. Then tell your partner that you never trusted him since the beginning and then he's gonna fight you, but the traitor's gonna be backed up by the tag team champions making the match a handicap match.

The Rock at His Best
Choose The Rock in a Story Mode, (while he's not the champion), say no to the tag team op, win either Run Down or Talk Trash, (if you talk trash, than in the first interview, say that you want to kick his butt) win the next few matches until Wrestlemania, and than just before the match, The Rock will be interviewed and will do what he really does!

The Pile o' Tables
In a TLC Match or a Table match, take the table outside of the ring and throw it at the announcers table it should land on the announcers table. Climb on the table and while holding the down button pick up the table then try to set it up. It should be set on top of the other table. You can do high damage moves through the 2 tables. This can also be done with 3 tables.

Insurextion Arena
This is a very simple feature to unlock and it will unlock the Insurextion arena which is Smackdown Card 11. Turn down Vince for the Tag Titles, talk trash on the mic, in roaming, go down the stairs and go towards the snack machines where Michael Cole is. Talk to him and say you were just kidding, win the battle royal, talk to Hebert instead of choosing to go after the hard-core title. Then you will go to Regal's office - take the shot at the European title, win the match and the match that follows and you have the new arena.

See Kurt Angle In A Cowboy Hat
Choose Stone Cold Steve Austin in story mode (when he isn't the champ and the Rock is the Champ) and talk trash on the mic, say you were just messin', and win all matches up to WrestleMania. Then you will see Austin and Vince in a dressing room and Austin says something to the effect of "You'll Always be There" to Vince, then they hug. Then Kurt Angle enters the room shaking his head and wearing a cowboy hat.
