I am using osx terminal program to connect my iphone 3.0 beta 5.

selcuk-gorgulus-esprimo-mobile-u9200:~ selcukgorgulu$ ssh root@192.168.2.4

root@192.168.2.4's password:
Administrators-iPhone:~ root# apt-get update
-sh: apt-get: command not found
Administrators-iPhone:~ root#

where is my apt-get ? Is it normal for beta 5 or it is a problem ?
