Pagination problem on custom pages

Hi, I have been using Minamaze now for quite some time, and I love the theme. However I wanted to have some custom pages in order to display my categories rather than having dynamic URLs such as:

/category/phones

I wanted the physical page so my website read:

http://www.techradiance.co.uk/smartphones

Therefore I manually created these pages, and edited the PHP of page.php to the following:

<?php
/**
 * The template for displaying all pages.
 *
 * This is the template that displays all pages by default.
 *
 * @package ThinkUpThemes
 */

get_header(); ?>

<?php 

//Phones
if(is_page('404')){query_posts("cat=2");}

//Laptops
else if(is_page('654')){query_posts("cat=60");}

//Desktops
else if(is_page('667')){query_posts("cat=61");}

//Tablets
else if(is_page('656')){query_posts("cat=62");}

//Apps
else if(is_page('670')){query_posts("cat=63");}

//hardware
else if(is_page('758')){query_posts("cat=72");}

?>

<?php 

//If the page is the about page (ID 5)
if(is_page('9') || (is_page('5'))) { ?>
	<?php while ( have_posts() ) : the_post(); ?>

				<?php get_template_part( 'content', 'page' ); ?>

				<?php thinkup_input_allowcomments(); ?>

				<hr class="thickHR">

			<?php endwhile; ?>
<?php } else { ?>

			<?php if( have_posts() ): ?>

				<?php while( have_posts() ): the_post(); ?>

					<article id="post-<?php the_ID(); ?>" <?php post_class('blog-article'); ?>>

						<?php if ( has_post_thumbnail() ) {
							$column1 = ' two_fifth';
							$column2 = ' three_fifth last';
						} else {
							$column1 = NULL;
							$column2 = NULL;
						} ?>

						<header class="entry-header<?php echo $column1; ?>">
							<?php thinkup_input_blogimage(); ?>
						</header>		

						<div class="entry-content<?php echo $column2; ?>">
							<?php think_input_blogtitle(); ?>

							<?php thinkup_input_blogmeta(); ?>

							<?php thinkup_input_blogtext(); ?>
						</div>

					<div class="clearboth"></div>
					</article><!-- #post-<?php get_the_ID(); ?> -->	

				<?php endwhile; ?>

				<?php thinkup_input_pagination(); ?>

			<?php else: ?>

				<?php get_template_part( 'no-results', 'archive' ); ?>		

			<?php endif; ?>
<?php } ?>

<?php get_footer(); ?>

My issue now is that the pagination does not work with the code I have included, if I type:

http://www.techradiance.co.uk/smartphones/page/2

The same results show up.. when it should show up the same as shown on the category page:

http://www.techradiance.co.uk/category/smartphones/page/2

Does anyone know how to fix this? or a more simple fix, how could I import the code from:

http://www.techradiance.co.uk/smartphones/page/2

to my own custom page?

Many thanks in advance
