I just replaced my Sony Ericsson T610 that had busted due to going swimming
My previous T616 was an unlocked phone (previously Cingular)and when I set up the dialup number for use over bluetooth in the car and my PocketPC I used CID #3 ( *99***3# ). Oh, I have T-Mobile as a provider.
It worked fine and when using the proxy IP and port 8080, I was able to use my $3.99 T-Zones for internet without additional charges.

When I got this new phone, it was a branded T-Mobile phone and went to T-Mobile site and had the settings for everything sent to the phone.
OK, thats the background info.......

Now, I have multiple ways to get a connection. I am wondering if one is better than another and which one will not charge me for going over the data limit.
By sellecting " Connectivity - Data Comm - Data Accounts " this is what shows up under each data account :
TZones - CID = 1
TZones GPRS - CID =2
Picture Messaging - CID = 3
T-Mobile Internet - CID = 4

I am wondering if the " T-Mobile Internet " isn't left over from the previous owner, as I did not have that on the unlocked Cingular phone.

Does anyone have the same type of setup and can sled some light on this ???

Thanks
Don
