Assuming that your template is using Bootstrap (and most 3.0 templates will be), you can just add a special class to the module to hide it for phones. When editing the module, go to Options -> Advanced Options and look for a box to add a "Module Class Suffix". Add " hidden-phone" (space is important at the start since some modules don't put it there for you...) to hide for screen sizes less than 767px. Add "hidden-tablet" as well to the list (also separated by a space) if you want to hide it as well for 767px to 979px widths.

1I would like to point out that technically the module will still be loaded (I mean your users may noticed that on their mobile devices when using a mobile network). So the page will not be lighter. – Valentin Despa Apr 21 '13 at 14:19
I don't know if this is the best solution but it's a solution that I have now in mind.
You can use the JBrowser class
$browser = JBrowser::getInstance();
$browser->isMobile()
it returns a boolean value.
You can hide the modules from the template directly.

In the new version of bootstrap there is a new css names for hidding modules, check it on http://getbootstrap.com/css/
For example: "hidden-xs" stands for the old "hidden-phone"
But if you still have a truble and "hidden-phone" nor "hidden-xs" works. You can add this class by yourself:
Add this code to one of your Css files (your style.css or your custom.css):
@media (max-width : 768px) {
.hidden-phone {
display: none;
}
}
Then follow the advise above and add module class suffix to desired module.
When editing the module, go to Options -> Advanced Options and look for a box to add a "Module Class Suffix". Add " hidden-phone"
