Grand Theft Auto IV (health, wanted levels)

Before using cheat codes

You cannot enter any cheat code before your cellphone really works. Thus, you have to succeed the 2 first missions in order:

1) Drive to Roman's Place mission.
2) It's Your Call mission: go to see Roman at the cab depot, drive him to the hardware store, then back to the cab depot.
3) Now your cellphone works. Let's cheat!
