Usage you have to install gem rest-client and in application.rb you need to specify "require push"
You need to pass :app_id=> which you will get from bis server
:pass=> password provided for app id
:pin=> you can pass multiple like ["xxxxxxx","xxxxxxxxx"]
:content=>your message content.
:push_api_url=>(optional) if you have it you can pass it else default will be "https://pushapi.eval.blackberry.com/mss/PD_pushRequest"
Example
Push.new({:app_id=>"app_id" ,:pass=>"password",:pin=>["",""],:content=>"from Black_berry_push"})
That's it now you can use this gem for sending push-notification to any blackberry devices.
