Nokia N900: Validating Facebook Sharing - Network Error

Recently I got the error message, "No network connection available, operation cancelled", when I try to add a facebook sharing account. The problem is with the curl library. We need to update it the to latest version. Add extras-devel, extras-testing repository if you cannot find the library in the stable channel.
Open terminal (Ctrl + Shift + X) and give the following commands:

root #change to root user
apt-get install libcurl3

Now re-validate your facebook account from the sharing accounts.

JQM: Refresh jQuery Mobile Select Menu

Suppose you are adding select menu to the page dynamically using JavaScript, jQuery mobile will not style the select menu. So have to refresh the select menu.

$('.mySelectMenu').selectmenu('refresh', true);

Sometime we might get an error like: "Uncaught cannot call methods on selectmenu prior to initialization; attempted to call method 'refresh'". To resolve it by first initialize the select menu and then refreshing it.

$('.mySelectMenu').selectmenu();
$('.mySelectMenu').selectmenu('refresh', true);

20 Nov 2012: Update with JQM 1.2.0 code explanation given below.
Make sure that the selector returns items which are all select nodes. Otherwise JQM will throw the above mentioned error. See the below JQM code.

// jQM v1.2.0: line 516
// ...
if ( isMethodCall ) {
    this.each(function() {
        var methodValue,
            instance = $.data( this, fullName );
        if ( !instance ) {
            return $.error( "cannot call methods on " + name + " prior to initialization; " +
                "attempted to call method '" + options + "'" );
        }
        // ...
    });
}
// ...

The code at line 6 checks for mobileSelectmenu property in the current element and assigns to the instance variable. If the current item is not select then the instance is null and we get the error.
