I want to implement my own realtime notification system (like facebook - when someone in my friends list comments on/likes my status, I'm notified about that)
I just want to know which technologies are best suited for such problem domain.
Thanks
It used to be AJAX, then there is now Comet. Just then, there is also HTML5 Web Sockets.
But i guess what is prevalent to your situation at present may be solved by Comet.
Its called pushed notification.
AJAX can be used in a pull notification manner, i.e. browser periodically checks the server for updates. Comet is for push notification, i.e. server sends updates to the browser.
Web Sockets is only relevant in HTML 5 enabled browsers.

Is it possible in iPhone if we can track users actions? Like which applications he has opened, sent messages or calls etc.
Thanks
Simple answer: no
Apps cannot access the usage information of different apps.
There is a (work arround) solution by implementing a Proxy-App, which provides a proxy server and registers this proxy server in the preferences. All network data would pass that proxy and your Proxy-App could send usage statistics to your server.
However, you can only track network traffic, not other usage statistics. Moreover, this App would never pass the App Review process...

I need to know if it is possible to develop an application to read and reply to SMS and email. If so, how could this be done (what library/class needs to be used). I've searched all apps there isn't an app that does this. There's only an app that requires you to set your email and constantly checks for new message however SMS I'm not sure if there's an app that does this thereby I'm not sure if it could be done. Thanks,

Without a jailbroken iPhone, no. You can't interact with the other native applications beyond what the APIs provide (i.e. accessing the photos and media library). Like the other e-mail application, you could fake the e-mail situation by requiring them to provide you their servers and credentials. However, you really can't access the SMS history nor respond to them.

I want to create a chat sort of application on the iphone. I know how I would go about implementing a poll model, where the iphone would poll the server to see if any messages have arrived and if they have it can retrieve them and show them to the user. However im more intersted in a push model, where the server pushes new messages to the iphone and it displays it to the user. The part im having a hard time figuring out is how to go about opening some permanent connection on the phone that will listen for incoming messages...Any suggestions or comments would be appriciated..
Thanks

The iPhone 3 SDK has push support built in. Basically, all messages that need to be pushed (from all apps) go to Apple's server, which maintains a persistent connection to the user's iphone. The upside is that you dont have to worry about it and your app can get updates even when its not running (so like, from the home screen). The downside is that your data has to go through Apple's server.

Same as the above question.
Probably the only way would be to send the work off to a server to do the work, and have that server send a Push message to the phone when it's complete. That would notify the user that the task has been completed, so they could then reopen the app and continue. But running something locally on the phone while the app is closed isn't allowed by the API.
If you're referring to background processes, the answer is currently no. This is a controversial issue with iPhone app dev at the moment as there is no way to perform background processing (afaik).

How to implement Push notification in iPhone?
The Apple documentation on Push Notifications is very clear, with sample code:
http://developer.apple.com/iphone/library/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/Introduction/Introduction.html
If you aren't interested in implementing your own server solution for providing push notifications to your client, you might be interested in these solutions:
http://appnotify.com/
http://urbanairship.com/push/
Each charge a fee for push notifications sent, but they also abstract away most of the initial setup complexity and, obviously, the costs associated with maintaining one's own server/bandwidth.
If you're interested in hosting your own solution, I've had success with Apns4r, a Rails plugin: http://github.com/searls/Apns4r
There is also an open source python Apple Push Notification server, in case you want to roll your own and don't fancy any of the options that Justin mentioned.
