There is no DHCP in GSM.  The settings are obtained via underlying 
network to mobile signaling.  How they are provided to the telephony 
stack varies.  In the case of PPP it is done via IPCP.  Some modems fake 
a DHCP server in their firmware, and some provide the settings via AT 
commands.

There is no gateway because the link is point-to-point, it isn't necessary.

For your question regarding GPRS vs 3G.  The commands used are the same. 
  The modem capability and network availability will determine the 
technology used.  Really the only difference will be the speed you 
connect at.  PPP is too slow for true 3G speeds.  This is why most modem 
manufacturers have switched to high-speed interfaces (e.g. faked 
ethernet) or other special extensions.
