If you want to communicate with an existing server you’ll need the iPhone app to implement whatever communications protocol that server supports. In the MYNetwork framework, the TCPConnection class (the parent class of BLIPConnection) gives you access to the input and output streams and lets you send/receive whatever data you want. You’d need to use that to talk to the server.

As for having the server connect to the iPhone, there’s no good way to do that unless they’re on the same LAN. Especially not over 3G, because AT&T doesn’t allow incoming IP connections over 3G.

BUT PLEASE CAN ANY HELP ME OUT HOW TO IMPLEMNT THE CHATTY ON INTERNET USING THE REMOTE SERVER I HAVE(MY SERVER IS CURRENTLY A UNIX SERVER AND CAN BE SHIFTED

I JUST WANT TO COMMUNICATE BETWEEN IPHONE AND MY SERVER USING REMOTE OBJECT OR SOMETHING LIKE REMOTE OBJECT SO THE SERVER CAN PING THE IPHONE DEVICE AND THERE IS NO DEDICATED TCP/IP CONNECTION EXISTS.

And there are some non-game apps that allow nearby users to share data, like the one for address cards. There’s also an open-source app that lets you drag photos from one iPhone to another; that one actually uses MYNetwork and BLIP :)
