Hello all from Glasgow, Scotland.
I have recently purchased a BB7230 off ebay, with SIMlock to Voafone(UK). I _dont_ have a BES or BIS account and have a Pay as You Go (pre-pay) Vodafone SIM. I mainly intend to use the BB as a Phone /PDA but a bit of TCP/IP access would be nice.
The Vodafone SIM works fine on GPRS in other mobile phones I can use my laptop and the IR port on my Nokia for internet access on most ports (80,21,23,8080 etc).
I found these very helpful forums via Google so rather than just ask for help I though I would share my learning so far for others to find - and then post my question immediately below this...
Removing the IT policy
====
I downloaded the BB desktop software but could not install applicatios so I followed the instructions here:
http://blackberry.ig3.net/
Other people have reported mixed results, but it worked fine for me and I can now download and install software via the desktop.
TCP / IP Access
====
I entered APN pp.vodafone.co.uk user:web, password:web (exactly the same as on my Nokia phone)
I have no Blackberry browser and know of no method to get it back so I then downloaded Opera Mini and installed it.
During first start up it goes through a number of staps before failing with an error:
The application operette$2dhifi has attempted to open a connection to a location inside the firewall and outside the firewall which is not allowed by your it policy.
Googling round a bit this seems to be due to a policy restriction, that is turned on by DEFAULT in the BLANK profile to DISABLE split-pipe-connections. See:

AFAIK since OS version 3.61 an application can only connect via wither the BES/MDS _or_ TCP/IP - the first service it connects to (even if it does not work) is remembered unless you remove all the software and reinistall. See link below for how to make the BB "forget":

So I then installed a trial of IM+ that allows you to select the transport mode TCP/IP or MDS/BES or BIS and I also installed a trial of Idokorro Mobile SSH that allows you to pick TCP/IP, BIS or BES/MDS.
In both cases with the software set it TCP/IP I get as far as the "arrows" flashing in the top right of the screen the the BB transmits (I can hear the interference on a radio) with no firewall problems.
