title: presentModalViewController is not working on device iOs 4.0.1 jailbroken
body: <p>I am trying to present a modelViewController, it works perfectly on iOs 5 device and Simulator, on iOs 4.3 simulator but it does not work on iOs 4.0.1 jailbroken device.
  I try to debug my code, the viewController is initialize but the method viewWillAppear is not being called on my device with iOs 4.0.1 jailbroken.It is being called on all other devices.
  here is my code</p>
  
  <pre><code>loadingView=[[UpdatingVc alloc]initWithVar:var1 andVars:var2 andVarz:var3]; 
  [self presentModalViewController:loadingView animated:YES];
  </code></pre>
  
  <p>I hided the original var names with the main varNames for security reasons.
  the init Method is :</p>
  
  <pre><code>-(id)initWithVar:(NSString*)var andVars:(NSString *)vor andVarz:(NSString *)vers{
  self = [super initWithNibName:@"UpdatingVc" bundle:[NSBundle mainBundle]];
  if(self) //good practice to check first
  { 
     _a=var;
     _b=vor;
     _c=vers;
  } 
  return self;
  }
  </code></pre>
  
  <p>Thank you</p>
