No since it does not support Series 60 devices.
- How about Java language (JNI) for my apllication?
Hmmm... see further.

Hmmm... see further.
- What will I use other tools or SDK?
You can either use AT commands (search through previous discussions here and Forum Nokia for AT) or/and go to www.symbian.com and search for mRouter based pc connectivity solutions.
