Delay when refreshing UITableView custom cell

I have a UITableView with a custom cell which i fill (with array infoservices) after parsing the xml data.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
 {
     static NSString *CellIdentifier = @"Cell";
 
     ApplicationCell *cell = (ApplicationCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
         if (cell == nil) {
             [self.cellNib instantiateWithOwner:self options:nil];
             cell = tmpCell;
             self.tmpCell = nil;          
         }       
 
         infoService *e = [self.infoservices objectAtIndex:indexPath.row];
 
         cell.name = [e  infoName];
 
         NSString *infodetails = [e infoDetails];
 
         if ( infodetails == nil ) {
             cell.details = @"Loading...";
             [self startInfoDownload:e forIndexPath:indexPath];
 
             NSLog(@"Loading...");
         } else  {
             cell.details = infodetails;
             NSLog(@"Show info detail: %@", infodetails );
         }
         return cell;
 }
 
 
 - (void)infoDidFinishLoading:(NSIndexPath *)indexPath
 {
     infoDownloader *infoserv = [imageDownloadsInProgress objectForKey:indexPath];
     if (infoserv != nil)
     {
 
         [infoservices replaceObjectAtIndex:[indexPath row] withObject:infoserv.appRecord];
 
         NSIndexPath *a = [NSIndexPath indexPathForRow:indexPath.row inSection:0]; // I wanted to update this cell specifically
         ApplicationCell *cell = (ApplicationCell *)[self.tableView cellForRowAtIndexPath:a];
         cell.details = [[infoservices objectAtIndex:[indexPath row]] infoDetails];
 
         NSLog(@"Updating=%@", [[infoservices objectAtIndex:[indexPath row]] infoDetails]);
     }
 }
 

For each cell i'm using NSURLConnection sendAsynchronousRequest to retrieve and parse xml data from object infoDownloader with

- (void)startDownload
 

for each individual cell.

After data has been successfully parsed delegate method from infoDownloader is called

- (void)infoDidFinishLoading:(NSIndexPath *)indexPath
 

The problem is that, while the

- (void)infoDidFinishLoading:(NSIndexPath *)indexPath 
 

gets called after parsing each cell and i can see the

NSLog(@"Updating=%@", [[infoservices objectAtIndex:[indexPath row]] infoDetails]);
 

in the debugger with the correct details, the cell does not get refreshed immediately but after 6 or 7 seconds. Also cellForRowAtIndexPath does not get called from

- (void)infoDidFinishLoading:(NSIndexPath *)indexPath 
 

for some reason because there is not debug output after the infoDidFinishLoading. Also i don't understand how the cell.details gets actually refreshed since cellForRowAtIndexPath isn't called again.

I've tried to setup this function using Apple's LazyTableImages loading example, which i have used successful, but i don't know what's going wrong.
