Weird behavior of iPhone tableview not occurring on iPad

I have build a grouped tableview with 2 sections.

There always have to be 1 selection in each of the sections, and there can't be more.

This is working rock steady when testing on the iPad.

I recently started developing the xib for the iPhone version.

Now things start getting weird. When scrolling the selections fly all over the place, disappears, and sometimes there are 4 selections in a section.

The exact same code is working flawlessly on the iPad.

Is there any known bugs that might make this occur?

UPDATED WITH CODE:

        - (void)viewDidLoad
    {


         [super viewDidLoad];
         self.view.backgroundColor = [UIColor whiteColor]; 

    //Initialize the array.
    listOfItems = [[NSMutableArray alloc] init];

    NSArray *countriesToLiveInArray = [NSArray arrayWithObjects:@"Baskerville", @"Palatino", @"Times New Roman", @"Verdana", nil];

    NSDictionary *countriesToLiveInDict = [NSDictionary dictionaryWithObject:countriesToLiveInArray forKey:@"Countries"];

    NSArray *countriesLivedInArray = [NSArray arrayWithObjects:@"My Text", @"My Text", @"My Text", @"My Text", @"My Text", @"My Text", @"My Text", @"My Text", @"My Text", @"My Text", @"My Text", @"My Text", nil];

    NSDictionary *countriesLivedInDict = [NSDictionary dictionaryWithObject:countriesLivedInArray forKey:@"Countries"];

    [listOfItems addObject:countriesToLiveInDict];
    [listOfItems addObject:countriesLivedInDict];

    //Set the title
    self.navigationItem.title = @"Countries";  

}

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];    

     NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];

    //SET Font 
    NSString *neverOpendFonts1 = [prefs objectForKey:@"neverOpendFonts1"];

TSolved the problem... Got my answer on iphonedevsdk.com...

I added

if([self.lastIndexPath1 isEqual:indexPath]) { cell.accessoryType = UITableViewCellAccessoryCheckmark; } else { cell.accessoryType = UITableViewCellAccessoryNone; }

to the cellForRowAtIndexPath

and added

if(self.lastIndexPath1) { UITableViewCell* uncheckCell = [tableView cellForRowAtIndexPath:self.lastIndexPath1]; uncheckCell.accessoryType = UITableViewCellAccessoryNone; } UITableViewCell* cell = [tableView cellForRowAtIndexPath:indexPath]; cell.accessoryType = UITableViewCellAccessoryCheckmark; self.lastIndexPath1 = indexPath; }

to didSelectRowAtIndexPath...

I removed the old `/*

    NSInteger oldRow = (lastIndexPath1 != nil) ? [lastIndexPath1 row] : -1; 

    if(newRow != oldRow) 
    { 
        newCell.accessoryType = UITableViewCellAccessoryCheckmark; 
        UITableViewCell *oldCell = [tableView cellForRowAtIndexPath:lastIndexPath1]; 
        oldCell.accessoryType = UITableViewCellAccessoryNone;
        lastIndexPath1 = indexPath; 
    }   

           */`

from didSelectRow, and now everything works perfectly...
