 Or with a little more work you can make the entire thing transparent by  
 setting up a VPN on one of those ports and just directing linux to route  
 all traffic over the VPN.

i'm sure, if it was that easy to circumvent the restrictions imposed on a  
5$ plan, t-mobile would have dropped it already.

Normally it is. If the provider allows you to access SSL sites,
there's not much the can do. Google for proxytunnel.

Well that's not really easy. Remember, this is a mobile phone. So 
it's either completely closed or closed enough to make a project like that 
exceedingly difficult. So unless you happen to have a truly open phone (say, 
one running openmoko?) it's close enough to impossible that the carriers don't 
worry about it. And it'll probably take a lot of openmoko-based phones doing 
this before it becomes worth their time to try to plug the hole.

If you think that's funny, T-Mobile wifi (in the US) allows you to route 
port 53/UDP to the world before you pay them.  So OpenVPN to a machine on 
port 53 and you're golden.

There is a common mistake in the geek community that once people are aware 
of the problems, they fix them.

I'm guessing that their current lineup of phones are so locked up in 
terms of software ability, it's never been *tried* before on TMobile's 
network? Perhaps I'm wrong.

That is exactly right.  I thought I read about some work around for the 
port restriction, but I didn't dare to try it so I stuck with the add-on.

 So with T-Mobile they have a web and email option for like $5 / month

 is like $40 / month.  Does anybody have these plans and will I be able 
 to use the FreeRunner as a web device with the $5 plan?
 

 I don't have any first hand experience with T-Mobile data plans, but 
 this site might help you:

 http://wiki.howardforums.com/index.php/T-Mobile_Data

 It looks like the $5.99/month plan really is unlimited, but there are 
 port restrictions.  The $19.99/month plan has no restrictions.  These 
 are both add-ons for people with a voice plan.  The more expensive plan 
 is a stand alone data plan.

 At least that's how I read it.  Anyone who knows better feel free to 
 correct or expand.

Well, in theory, if you're writing your own app and have a spare IP
address, you could write the app to answer on port 12345 and configure
that IP address via iptables to listen on port 80 but forward internally
to your app on port 12345. Pretty simple redirection.

What I have done in the past is use 'ssh -D' to create a local SOCKS 
proxy to tunnel to another machine running SSHD on port 993.

There are weird latency effects involved in laying all your connections 
over a single TCP connection; better would be see if one can abuse TCP 
packets to a remote port 993 and treat it as UDP, and then do OpenVPN. 
(Or just see if you can do UDP on that network.)
