What interfaces are programmable in the Nokia N73?

I have a Nokia N73 and I'd like to program it to interface with external hardware using any available interface. (POP Port?)

Using any of the available platforms:

• Open C++
• Symbian C++
• Java
• Flash Lite
• Python

Found:

• Java ME Serial Port, RS-232 CommConnection using Java ME MIDP
• Wired Interfaces on Nokia mobiles, USB, POP, AV, 2mm
• Serial communication over USB, using the RComm API in Symbian C++
• IR Serial communication, using the S60 Comms Server
