Try changing this line:
if (req.status == 200) {
into:
if (req.status == 200 || req.status == 0) {
on mobile devices running from the file:// protocol you often get a status of 0 when there is a successful request.

What result do you get in Chrome? Chrome and the Android Browser (along with Safari and the BlackBerry Browser) are all based on WebKit.
Have you added access origin to your phonegap.xml file?
Is there any particular reason you're not using jQueryMobile for your AJAX? Are you able to get a successful response using jQM?

var url = 'http://localhost/prestashop/api/customers/2?PHP_AUTH_USER="password"&ws_key="login"';
