Since v.1.4 this procedure is simplified, just change the following lines in config.h file:
// specify site you want to lock to, for example: #define BX_LOCK_APP @"mysite.com/dolphin"
#define BX_LOCK_APP nil
It will add your site by default, when application is started the first time, so before starting the first time delete already exists OO application if there is one.
