I am working on pubnub j2me sdk and want to implement push notification in j2me as there is no regular platform to automatically run the application as in iOS, so socket/datagram pushregistry (don't want sms pushregistry) is the only option to do this task.
But I don't know how to implement this for pubnub j2me?
I suggest you reconsider SMS push registry as sockets/datagrams push doesn't exist for J2ME.
