Here's a full working example of how to allow querystrings in Codeignitor, like on JROX platform. Simply add this to your config.php file located at:

/system/application/config/config.php 

And then you can simply get the querystrings like normal using $_GET or the class below

$yo = $this->input->get('some_querystring', TRUE);
$yo = $_GET['some_querystring'];

Here's the code to make it all work:

/*
|--------------------------------------------------------------------------
| Enable Full Query Strings (allow querstrings) USE ALL CODES BELOW
|--------------------------------------------------------------------------*/

/*
|----------------------------------------------------------------------
| URI PROTOCOL
|----------------------------------------------------------------------
|
| This item determines which server global should 
| be used to retrieve the URI string.  The default 
| setting of 'AUTO' works for most servers.
| If your links do not seem to work, try one of 
| the other delicious flavors:
|
| 'AUTO'              Default - auto detects
| 'PATH_INFO'         Uses the PATH_INFO
| 'QUERY_STRING'      Uses the QUERY_STRING
| 'REQUEST_URI'   Uses the REQUEST_URI
| 'ORIG_PATH_INFO'    Uses the ORIG_PATH_INFO
|
*/
if (empty($_SERVER['PATH_INFO'])) {
    $pathInfo = $_SERVER['REQUEST_URI'];
    $index = strpos($pathInfo, '?');
    if ($index !== false) {
        $pathInfo = substr($pathInfo, 0, $index);
    }
    $_SERVER['PATH_INFO'] = $pathInfo;
}

$config['uri_protocol'] = 'PATH_INFO'; // allow all characters 

$config['permitted_uri_chars'] = ''; // allow all characters 

$config['enable_query_strings'] = TRUE; // allow all characters 

parse_str(substr(strrchr($_SERVER['REQUEST_URI'], "?"), 1), $_GET);

Enjoy :-)
