Packet Data Access Point Names vs real data server...

Question

I am trying to activate an application that requires GPRS.
I currently can get EGPRS and assume that will do the same but faster. But I have a question that may not pertain to this but as I am new at this I will ask it here. From reading I see that the settings of packet data appear to have more to do with setting up phone as a modem to use. So I don't know truly if this has any bearing on my problem with the software registering to complete the setup of it.
However my web access which is unlimited month to month internet access which allows me to go anywhere on web (not a walled garden) also uses this GPRS or EDGE version of GPRS. I am in the USA with T-Mobile. Phone is set to use GSM. The screen where it concerns connectivity says that I have Access Points which were configured by T-Mobile sms file they sent me twice. I actually have 5 names under Access Points.
1)MMS = wap.voicestream.com
2)T-Mo WEB = Internet.voicestream2.com with small i in settings
3)T-Mo WEB(01) - this from 2nd sms copy same
4)T-Mobile Internet = Internet.voicestream2.com with small i in settings too.
5)t-zones this is their wall garden = wap.voicestream.com
ok since I can browse the web anywhere and download the application I don't know why I cannot register it. But it states it needs an internet connection before activation through authentication, or basically registering it to use.
So I am trying to do this after verifying that I have an internet connection with the too connection arrows symbols on phone screen showing internet connectivity with E over them currently by starting a browser first as the application doesn't seem to do this for me when trying to activate it.
E
--> where the lines are solid. Ok here is my issue here.
The arrows are not coming up correctly in this forum anyway I get what shows I have EGPRS connectivity, I don't know if the application is sensitive to using GPRS only but will find out. I doubt it. The GPRS would show the arrows with an antennae above. I am talking about the indicators from what the pdf and book say.
Below Access Points on the menu in settings for connection is Packet data.
Packet data has to variables
1) when needed , or when available
2) Access point
Access point is blank. Should I enter one of T-Mobiles names in the list above this under Access Points such as
T-Mobile Internet or should I put the server name in specifically internet2.voicestream.com?
I set the Data Call setting to Unlimited to make sure if its using this process it doesn't turn off after the 5 minute default on the next setting.
Any ideas why this gprs app is not activating itself and making the gprs internet connection with the pin I was provided? I had to use the pin just to download it and install it.

Answer 1

that will work. You only need to change if you need to have always on (highly unlikley) or if you are using modem dial up and need to specify access point for that.
If you using Nokia One Touch access then you don't even need to define access point in this menu as that application will take care of it for you.
All other network aware applications will use access point settings as defined in settings menu.
