tiny application server on a mobile

[Ankur Jain Kothari]

Is it possible to directly access the operating system of a s40 mobile and create a server internally which will keep listening on a particular port for any pushes I sent to it from my application server? I wonder how whatsapp is able to send pushes to my nokia asha 301 phone?

You don't need to create a server (I doubt you can even do that)
What you need is Push Registry
