                    CGRect frame;
                    frame.origin.x = 70; 
                    frame.origin.y = 15;
                    frame.size.height = 25;

                    cLabel.backgroundColor = [UIColor clearColor];
                                        cLabel.text = [NSString stringWithFormat:@"%@", aDetail.telnumber];


                    cLabel.backgroundColor = [UIColor clearColor];


                    cell.backgroundView = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"r1.png"]] autorelease];

                }

                break;

You Really should cleanup youre code before posting here!

It is very hard to read and you have many errors, whitespace and commented-out-lines in it that you should remove..

Read http://developer.apple.com/iphone/library/documentation/userexperience/conceptual/TableView_iPhone/TableViewCells/TableViewCells.html#//apple_ref/doc/uid/TP40007451-CH7-SW15 It should help you get started with custom cells..

Basically all the customization should go in:

if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
      //Customization here:
}

The way you do it you are allocating labels every time a new cell is displayed instead of reusing..

It seems like youre cells are static. You only have one cell per section and dont need reusing the cells? If so maybe it would be easier to create static cells with interfacebuilder http://developer.apple.com/iphone/library/documentation/userexperience/conceptual/TableView_iPhone/TableViewCells/TableViewCells.html#//apple_ref/doc/uid/TP40007451-CH7-SW32
