hi
in the option menu of BB you shoul find
My instant Communicator
if not present , reboot your device (i experience same issue)
you may have to force a rebbot by removing the battery
retry to download again the application
in the option
you have to
put ICS url for configuraiton URL =
http://ics.company.com
BB will use it to access configuration files
http://ics.company.com/DM/BlackBerry/xxxx.xml
then use BB menu button to load such config fie present in ICS
and complete w this by the password
take care also to put MDS url
http://ipofyourBES_MDS_service:8080
when applicaiton is running
on the MYIC screen
press ALT and maintain button ALT and input LOGS
