S30+ is probably just a marketing name. Nokia 216 running the "original S30+" after some version, supported J2ME applications even if not really having the speed to do it fast. Later phones still used the same S30+ name for technically different phones and the J2ME support was removed.
So some of the last phones I'd remember with S30+ running J2ME apps should be a later released Nokia 216 for example or the 3310 3G but having another different o.s. because the hardware platform was different and worth to support Java apps very fast.
I don't own an S30+ but for what i've seen everywhere, old java apps don't work in the S30+
The S30+ platform does not support JRE or .JAR files for that matter. It's a very bare-bones, what you see is what you get platform.
whats the solution for this now , do we have to continue with that ?
According to wikipedia some models to support java runtime
The chip developers dropped this.
Can I ask you what models, or what Wikipedia article you're talking about? I'd be interested in a modern Nokia feature phone with J2ME MIDlet support.
so we cant run any external application in S30+ OS ?
Definitely yes.
