On some phones, the user can update the application manually, if the application was installed via OTA (I guess the phone saves the jad url, then it compares the midlet version): the user just have to go to the application menu and check the right option.

Otherwise, your server solution seems alright. Then if there is a new version of your application, you'll use the midp2 method, MIDlet.platformRequestion(JAD_URL), to "update" the application. Actually it reinstalls the app again, and it may ask you if you want to keep the former RMS data.

Hi nekinpatel,

This is what canard_42 talked about.

Invoking Platform Services in MIDP 2.0

Note that it is MIDlet.platformRequest and not MIDlet.platformRequestion as below

Hope it helps
