For WPML versions >=3.2 please use the wpml_object_id filter hook. The function shown below can still be used but it has been tagged as deprecated

E.g.

// will return the post ID in the current language for post ID 1
echo apply_filters( 'wpml_object_id', 1, 'post' );

// will return the category ID in the current language for categoy ID 4. If the translation is missing it will return the original (here: category ID 4)
echo apply_filters( 'wpml_object_id', 4, 'category', TRUE, );

// will return the German attachment ID for attachment ID 25. If the translation is missing it will return NULL
echo apply_filters( 'wpml_object_id', 25, 'attachment', FALSE, 'de' );
