//Background of AlertView is an image And you can change this image

UIAlertView *theAlert = [[[UIAlertView alloc] initWithTitle:@"Your Title"
message: @"Your Message Here"
delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil] autorelease];

[theAlert show];

UILabel *theTitle = [theAlert valueForKey:@"_titleLabel"];
[theTitle setTextColor:[UIColor redColor]];

UILabel *theBody = [theAlert valueForKey:@"_bodyTextLabel"];
[theBody setTextColor:[UIColor blueColor]];

UIImage *theImage = [UIImage imageNamed:@"Background.png"];
theImage = [theImage stretchableImageWithLeftCapWidth:16 topCapHeight:16];
CGSize theSize = [theAlert frame].size;

UIGraphicsBeginImageContext(theSize);
[theImage drawInRect:CGRectMake(0, 0, theSize.width, theSize.height)];
theImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

[[theAlert layer] setContents:[theImage CGImage]];
