your pressing something wrong, press up on your d-pad.
you cant really open it but you can break it open
yes , but you can't use it
To enter cheats, dial the number using Niko's Cell Phone...To access more cheats, open the phone, go to the menu and scroll to cheats :)
you have to finish the fifth mission i cant remember whats the name of it but when you finish it you get the cell phone and you will be able to type in cheats all you do is click the up button twice
use the cell phone
nope
I Think you press the up button on ps3 and xbox i dont know how you do it in pc
do the first misson or second just do some missions then u will get the phone
put in the cheat on the cell phone
you cant dial letters only numbers hope this helps
if you mean take out of your current game you just quit or from the phone you cant
You Can't. Go Buy Grand theft Auto IV, That game has a workable Phone.
