Last home screen provides wallpaper for Dell Streak lock screen
If you ever find yourself among other Dell Streak owners and you all put your devices down on the table for some reason, don't rely on what you see when you press the power button to figure out which one is yours. Because unless you disabled the lock screen, the wallpaper you'll see may not be what you're using on your main home screen.
Since each home screen on the Streak can have its own unique wallpaper, you'll probably end up using six different ones. And this is why you can mistakenly pick up someone else's Streak and think it's yours. Unlike other Android devices that let you choose a wallpaper specifically and exclusively for the lock screen, the Streak displays the wallpaper on the home screen that you used last.
So if you unlock it, go to another home screen, put it into standby, and awaken it again seconds later because you forgot to check something, you'll see a different wallpaper on the lock screen. This can be a little jarring if you're not expecting it, especially if some of your home screens are less used than others.
