Is it possible to develop custom application on the BlackBerry device that use standard TCP/IP to communicate with internet services WITHOUT a BES? Or does the BIS restrict internet connectivity to email and chat?

Additionally, can you push data (MDS services) to a BlackBerry handset WITHOUT a BES?

Thanks in advance,

Chris

yes, it is possible to use tcp/ip without BIS.
no, it is not possible to push data from MDS without BES server.

read BlackBerry Developer Guide and look at the samples, attached to the JDE - it should help you.

i think he meant 'without bes' :P

you can use tcp/ip on bis but you cannot perform push operations, that requires a bes.

Thank you for the quick replies.

A follow on question. I have a BB Pearl linked with a BES with MDS services turned on. I test the JDE SocketDemo app via the simulator and I was able to communicate with a socket server I have running in my internal network. I then compiled the socket demo and placed it on my Pearl. I tried running the same socket demo and it hangs while trying to connect. I specified the correct IP address and I even was able to telnet to the socket from the actual BES machine.

Does anyone know why my BB is failing to connect via the socket demo? I have TMobile service.

jfisher - yes you are right

knifegun - maybe problem is with internal address?
if address is available only from inside your LAN, you can't access it from your Pearl, which is "outside".

There were two problems. One of them is that I needed to setup the APN on my phone via the FAQ even though it is connected to the BES. Once I did that, I needed to ensure to connect to an external address. This means that my TCP/IP connection did not go through the BES which is pretty cool.

Thank you all for your help!
