I made this mini mod a while back for the STM Mobile Tracker V4 (P202) and looks like some of you guys would find it useful so here it is.
It will send the country name to your landing page by appending it to your URL during the initial redirect.
When you generate a tracking/redirect link, use the option 'Yes. (GET parameters supported: carrier, brand, os and model)' and '&country=[Country]' will be appended to your URLs.
E.g. 'landingpage.com?subid=1337&country=Australia&carr ier=...etc.'
To mod your installation, all you have to do is edit/replace:
\webapp\tracking202\redirect\tracker.php
I have attached a pre-edited tracker.php file to this post, I couldn't put the whole code up here in text because it was too long.
Alternatively you can make two small changes to the tracker.php file yourself:
First Edit - Find (line 11)
function setTrackVars(){
global $mysql;
global $html;
function setTrackVars(){
global $mysql;
global $html;
global $ca;
$redirect_site_url .= '&t202id='.$tid;
my_log('pass_dev_info to: '.$tracker_row['pass_dev_info']);
if($tracker_row['pass_dev_info']==1){
$redirect_site_url .= '&carrier='.$html["carrier"].'&brand='.$html["brand"].'&model='.$html["model"].'&os='.$html["os"];
}
$redirect_site_url .= '&t202id='.$tid;
my_log('pass_dev_info to: '.$tracker_row['pass_dev_info']);
if($tracker_row['pass_dev_info']==1){
$redirect_site_url .= '&country='.$ca.'&carrier='.$html["carrier"].'&brand='.$html["brand"].'&model='.$html["model"].'&os='.$html["os"];
}
Nice mod!
I continue to be amazed at how much functionality you can add to trackers with just a little bit of modding - definitely worth doing.
Awesome, can't wait to test it.
If it works with countries as well, it's just perfect. I'll try that.
Many thanks sir 
@Caurmen - Yeah definitely agree with you, I mean the STM Tracker in itself is an epic mod. I found this thread you started really interesting here. If you have the time, a tutorial on installing Mariadb and hooking it up to the STM Tracker would be massively appreciated!
@Julien - Glad it will be useful man!!
Post here if there are any issues with it.
Now we need some custom mod to add country flags next to the IP in Spy View 
Thanks for the share, it shouldn't add much ms to the redirect I assume
