Weird behavior of iPhone tableview not occurring on iPad - iphone

Question

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"];
if (![neverOpendFonts1 isEqualToString:#"1"]) {
lastIndexPath1 = [NSIndexPath indexPathForRow:1 inSection:0];
UITableViewCell *newCell = [myTableView cellForRowAtIndexPath:lastIndexPath1];
newCell.accessoryType = UITableViewCellAccessoryCheckmark;

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...
