I have been asked to investigate BB push and from what I can tell unless the user base is on BB OS 5.0 and above we are going to have to use Web signals. Our use base is fragmented with 50% being 4.6 and below and the other 50% on 5.0. Our production infrastructure doesn't use BES and I don't want to, I also prefer to stay away from a polling architecture.
With that said is there anyway to actually use the "new" BB push infrastructure on the client side w/o the 5.0 BB jars? Maybe by launching a application listening on a particular port ... it seems that these jars are mostly wrappers for xml ...
