I posted the settings here

But I'll post them again and answer the quesetion.
No, it's not just for DUN. The network profile you select in "prefs" > "Network" will be the one that all Treo applications (Blazer, 3rd party browsers, email, etc. etc.) will use. I believe this active network profile is also the one bluetooth DUN will use when it connects (I haven't used it in a while, so I don't remember.)
If you go in to Prefs > Network...
You should have 2 default entries:
Cingular GPRS
Cingular CSD
You should be using the "Cingular GPRS" setting. This setting is configured to use wap.cingular. So as you can see the default EDGE/GPRS network profile is the wap connection.
That setting has the following entries ("
Cingular GPRS" profile):
Connection:
GPRS
User Name:
WAP@CINGULARGPRS.COM
Password:
CINGULAR1 (it'll say 'assigned')
APN:
wap.cingular
Under Details: Fallback=NONE
To use the isp.cingular access point, you'll need to create a new network profile with the following settings.
I'd call it "
Cingular ISP" but you can name it anything you like.
Settings are:
Connection:
GPRS
User Name:
ISP@CINGULARGPRS.COM -OR-
ISPDA@CINGULARGPRS.COM
Password:
CINGULAR1
APN:
isp.cingular
(note ISPDA user name gives you enhanced compression, ISP user name is just normal without compression)
The easiest way to set up this new network profile is:
Go in to "Prefs" > "Network"
Select "Cingular GPRS" as your active network profile.
Select 'Menu' > 'Duplicate'
This will create a duplicate network profile called "Cingular GPRS Copy"
Edit the name to "Cingular ISP" (or anything you like.)
Edit the user name to "ISPDA@CINGULARGPRS.COM" from "WAP@CINGULARGPRS.COM"
Leave the password alone (it's already set to CINGULAR1)
Edit the APN to 'isp.cingular' from 'wap.cingular'
Click 'details' and make sure the fallback is 'none' (or you can set it to 'Cingular GPRS' if you like.)
Now just tap "connect." If it works, it'll log on and you'll get the green arrows near the signal strength bars sowing you're on. If it doesn't work it'll say "Signing on" followed by "Canceling" then nothing, no connection.
One more time:
$25 MediaNet and $20 MediaWorks should onlye be able to use "Cingular GPRS" (wap.cingular). If you can use isp.cingular you're lucky.
$40 PDA plan can use wap.cingular or isp.cingular (Some people say they can use it, some say they can't. You'll have to give it a try.)
$80 Data Connect should use isp.cingular
Cingular CSD is "Circuit Switched Data." It's the old GSM data connection that actually places a phone call (using your minutes) and is basically ISDN over wireless. It has a limit of 9kbps (very very slow.)
If you can use it, you're lucky or grandfathered in. To add it is $3/month and you have to call Cingular and ask them to add "Data Access CSD" or "Wireless Internet (CSD)" or you can add it from your account management on Cingular's web site. It only works on Cingular's native network (won't work when roaming) and is otherwise not worth paying for.
