Nokia 6230 developer analysis
Peter Rogers’ brain dump of J2ME and related developer issues for the Nokia 6230 (part of a 6230 thread on the kvm-interest list) is worth a read for anyone interested in J2ME MIDP 2.0 development on Developer Platform 2.0 for Series 40 devices (the 6230 is the reference device).
Why this program make VM of Nokia 6230 broke reboot？
