Settings for Orange internet - how?

I've managed to find out that the settings I need to make the internet etc available on my pulse on orange are as below:

Name: Orange GPRS WAP
APN: orangewap
Proxy: 192.168.71.35
Port: 8080
Username: Orange
Password:
MCC: 234
MNC: 33
APN type: default
Leave all the other options blank

However when I choose a network ("Orange" doesn't always come up, though there are 3g and 2g ones which I an select) and then select "APN" I just get a blank screen with no fields to populate. What am I doing wrong?

 

Cheers "my other touchscreen device is an ipod touch" and I can't get used to hard buttons doing stuff.

Works a treat now.
