GSM is circuit switched data, i.e. like a normal modem connection. GPRS is only used to connect to the internet, so you will need to go through PPP sign in.

Some GPRS modules have the TCP/IP built-in, like the TC63i http://www.tdc.co.uk/index.php?key=tc63i for example, this makes it easier for non-TCP/IP aware devices to connect via the internet, send emails etc.
