Most of what you do in GTA IV still boils down to hustling jobs, stealing cars, trucks, and motorbikes of all makes and sizes, chasing and frequently stabbing, beating, or shooting enemies by land, sea, and air, and evading the law (only when you're caught, of course). Missions come in twos and threes and are usually conveyed through a convenient pop-up mobile phone, as are calls, contacts, text messages, and plenty of bling-tones if you've got the money and inclination to buy upgrades around the city.
The phone lets you manually dial outbound as well, which allows you to optionally interact with numbers cleverly strewn on or around signs and on websites in internet cafes sprinkled throughout the city - you can even dial 911 to summon a police car for help or just to engage in a little extra-brazen car-thievery.
Lining up money jobs through the phone's a snap, too, once you work yourself into the good graces of employers, who'll send you on missions ranging from taxiing patrons and vehicle jacking, to intimidating the stubborn or just plain stupid - even the occasional hired assassination.
