You can also try all tutorials for codeigniter 1.7 . To make them work in 2.0 mostly only cosmetic changes are needed
1) Models and Controllers in application folder should extend CI_Model and CI_Controller, respectively. (earlier there was no prefix ie, Model and Controller only).
2) constructer style should be changed to PHP5 ie, __construct (notice two underscores)
