UITableView backgroundColor always gray on iPad

When I set the backgroundColor for my UITableView it works fine on iPhone (device and simulator) but NOT on the iPad simulator. Instead I get a light gray background for any color I set including groupTableViewBackgroundColor.

Steps to reproduce:

1. Create a new navigation-based project.
2. Open RootViewController.xib and set the table view style to "Grouped".
3. Add this responder to the RootViewController:
   
   

   - (void)viewDidLoad {
   [super viewDidLoad];
   self.view.backgroundColor = [UIColor blackColor];
   }

4. Select Simulator SDK 3.2, build and run.
5. You will get a black background (device and simulator).
6. Select your target in the project tree.
7. Click on Project : Upgrade Current Target for iPad.
8. Build and run.
9. You will get a light gray background.
10. Revert the table view style to Plain and you will get a black background.

Thanks for your help!

Try one of these.

[myTableView setBackgroundView:nil];
[myTableView setBackgroundView:[[[UIView alloc] init] autorelease]];
