I am koushik, developing java mobile applications professionally. A j2me application was running successfully in every mobile handsets(h/s). After few months it is getting error at the time of download getting error type 'Invalid Application'; 'Connection not available'.
This is not a GPRS problem as the .jad file is being tracked properly neither .jar/manifest files have any conflict. This problem is being faced by (Specially) Nokia 6610 (Midp:1) people and some Sony Erricson(k700i, k500i) h/s.
I've concluded after a research that it might be Firmware related. If so, can anybody put some light on the remeady of the problem.
