Why my IP is not set?

Question

In Backtrack I entered this command :

vi /etc/network/interfaces

And then set these lines :

iface eth0 inet static
address 192.168.1.10
netmask 255.255.255.0
network 192.168.1.0
gateway 192.168.1.1

Saved and exited, then restarted my OS. But when I enter ifconfig command, it shows me that the:

inet addr :192.168.1.105

Why ?

I am sure that the previous vi command is saved because when I again enter command:

vi /etc/network/interfaces

the result shows me that:

iface eth0 inet static
address 192.168.1.10
netmask 255.255.255.0
network 192.168.1.0
gateway 192.168.1.1
