....and it has the BT logo on the front and on the inside. Its the Motorola with the grey front (of flip) and the blue backlight on the outer screen. When you turn it on or off it shows the BT logo on the main screen.

And im not talking about BT Cellnet, i'm talking about this BT logo

what?

I think we're a bit bemused about what your question is

Well basically if it shows that BT logo on its main screen when i turn it on or off, what SIM card does it take?

Unless its unlocked, it will be BT Mobile.
