WML = wireless markup language - an XML definition not unlike XHTML but
much more cutdown and geared toward, small mobile platforms (usually
with tiny screens and a limited input system - i.e. no 104-key keyboard :-)
quoting the site above:"
Because it uses the same protocols, the GPRS network can be viewed as a
sub-network of the Internet with GPRS capable mobile phones being viewed
as mobile hosts. This means that each GPRS terminal can potentially have
its own IP address and will be addressable as such.

lets not confuse the issue here - GPRS is NOT a protocol built on top of
HTTP - if anything its the other way around. GPRS is a physical network
spec (is my language correct there?) capable of hosting a TCP/IP
environment upon which HTTP can travel so to speak.

Jason is correct in this. a slightly different way would be to setup a
seperate site (e.g. vhost) geared purely to WML output (e.g.
wml.yourdomain.com) but the end result is the same.
obviously you will have to sort out the connection to the 'web' via your
phone. then its just a case of pointing it at you WML server to view a
page. when your at that stage you can actually get it to the fun side of
writing a secure php app that will output your email as WML pages....
hacing said that all those newfangled all-singing-all-dancing phones of
yester-minute have minibrowsers that are capable of viewing std (X)HTML
(e.g. the Opera mobile browser?) - in which case layout is your biggest
problem (i.e. cos of the small screen)....
there maybe a need to read/write special HTTP header 'by hand' in order
to fully communicate with the WML device... PHP give access to raw
request data so that should be a 'big' problem.
good luck on this - sounds interesting! keep us informed on how you get
on :-)
