dialing *99# from my laptop gets me this.

from my laptop to my work desktop

[[email protected] joelja]$ ssh -l joelja
ssh: connect to host port 22: Network is unreachable

ok how bout smtp 
[[email protected] joelja]$ telnet 25
Connected to
Escape character is '^]'.
220 ESMTP Sendmail 8.12.10/8.12.5; Tue, 17 Feb 2004 
17:55:03 -\080

that works, port 80
[[email protected] joelja]$ telnet 80
Connected to
Escape character is '^]'.
ok another host on another network (my home)
[[email protected] joelja]$ ssh -l joelja
ssh: connect to host port 22: Connection timed out

I haven't had any joy working through t-mobile on why they do this but it 
sucks and it makes my phone (nokia 3650) a lot less useful. Yes blotto 
has an ssh on an alternate port but that means hauling eveything back 
through there instead of being able to just connect back to the   whatever 
host I want.
