Yes it is possible to use a GSM phone as modem and connect to the 
internet through PPP, and mgetty+sendfax at the other end. There are 
some howto on the subject, I started a small one at 
http://www.pierrox.net/bluetooth_ppp/. Your phone must provide this 
functionnality, not all phones enable this.
However it won't be more than 9600bps. Such a slow rate is barely enough 
to read text emails, in general web pages are too heavy for 9600bps, and 
for example lots of images cannot be downloaded because of timeout. Also 
with this setup the ping is around 800/1000ms. 
However if you are patient and have unlimited minutes, it is certainly 
quite a good/cheap setup for basic internet tasks like ssh.
