I call it cell phone.
It's a phone that uses a portable cell battery to operate. -.- !
You could call it mobile phone, but that would imply that the phone itself moves. You know, like autoMOBILE. Self moving.
I against I,
flesh of my flesh,
and mind of my mind,
two of a kind but one won't survive,
my images reflect in the enemies eye,
and his images reflect in mine the same time,
