IPhone Web Service communication
<p>We need to write an iPhone application.</p>

<p>The application would need to consume an web service for storing user information, user session. etc.</p>

<p>Also one feature expected is, we should able to ping any user through iPhone application [iPhone would call web service and pass on data however bot sure how the webservice would pass that text to respective iPhone user].</p>

<p>I have searched on net for most feasible options on net and came accross some options like,</p>

<ol>
<li>Polling to web service.</li>
<li>WCF restful service for iPhone communication.</li>
<li>found some ready made servers for push to communication.</li>
</ol>

<p>Can you please suggest best suitable and cost effective solution.</p>

<p>Thanks in advance.</p>
