I am building an application using Jabber library from Bombus, it can run on emulator but when I deploy to real nokia 6630 device it does not work after I try to make a socket connection.

I tried to debug my program on real mobile phone but do not know how.
I am using Netbeans 5.0 RC2 + S60_2nd_FP3_MIDP_SDK. Someone know how to debugging on real nokia devices.
