iphone 3gs

I installed a new charging dock and when I thought I was done, this little black part was laying on the table. I cant figure out where it goes in the phone.....its the tiny black handle looking part with a screw hole in the middle on the far right in the picture (if I can get the picture to attach)

It's part of the sim card holder. It is the part that moves when you push in the sim tray opener. It goes up toward the top of the phone where the sim card goes in. I just did a 3G overhaul about a month back.
