"Pop-Up Alerts" integration on Blackberry Bold 9000

Hi Guys,

Recently, I have started working on Customer Portal project.
Project mainly deals with tracking the shipment, Client Order delivery, Poduct dispatched, Product received etc
Now, what I want is to integrate all above features so client can track it on any Blckberry devices (Blackberry Bold 9000, initially) in terms of "Pop-Up Alerts". i.e. Onces shipment got received to required location Client will get to know about shipment..
Could anybody knows how to integrate this?

Thanks...
