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?
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.
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.
