Finally, after a lot of faffing about [1] - sending from Norwich station using the BTOpenzone free trial. It's great when things finally work, isn't it!
[1] mainly because the username and password that was sent to me a few days ago proved not to work... ho hum. Good ol' BT...
Fortunately I was able to connect to the BTOpenzone site and re-register to get a new trial ID online.
Bit faster than Home Highway, too - pity the battery is running out - oh the joys of mobile computing:-)
