'No Transport' Error w/ jQuery ajax call in IE

I need to use foursquare API to search venues. Of course it is cross-domain.

It has no any problems in Firefox but in Internet Explorer (7, 8, 9 I've tested).

My javascript code looks like:

searchVenues: function(searchQuery) {
$.ajax({
url: 'https://api.foursquare.com/v2/venues/search',
data: {
sw: bound_south_west,
ne: bound_north_east,
query: searchQuery.query,
oauth_token: FSQ_OAUTH_TOKEN,
limit: 25,
intent: 'browse',
v: 20120206
},
cache: false,
dataType: 'json',
success: function(data) {
displayResults(data, searchQuery.query);
},
error: function(xhr, status, errorThrown) {
console.log(errorThrown+'\n'+status+'\n'+xhr.statusText);
}
});
}

In Firefox, it perfectly displays received data. In Internet Explorer, it logs on console:

No Transport
Error
Error

What should I do?

Thanks in advance.

tested this on Windows Mobile 7.

After LOTS of time spent to understand, I finally found this:

The Solution is simple, just set this:

$.support.cors = true;

and Ajax cross domain requests will work!
