I have a requirement for my new app, where i have to calculate Data uses, Type of Network,remaining uses and all like Data Usage app does. Can any one help me for the same How to i start. Thanks
if you want to know the type of network
look at Reachability , it's official!
The Reachability sample application demonstrates how to use the SystemConfiguration framework to monitor the network state of an iPhone or iPod touch. In particular, it demonstrates how to know when IP can be routed and when traffic will be routed through a Wireless Wide Area Network (WWAN) interface such as EDGE or 3G.

I am trying to prototype a solution to a problem and am currently exploring multiple routes I could try. Is it possible for one iOS device, running a certain app, to communicate directly with another iOS device, running the same application - without the need to be on the same LAN?
Solutions I am currently investigating are using Bluetooth and ad-hoc wireless connections.
Ideally, the application when installed would ask the user for the required permissions, and then would accept and/or send data to/from another client after a handshake had happened.
My concern with Bluetooth is that 'pairing' would need to happen with every device, rather than happen in the background once the user has installed the app. I have a feeling what I am talking about isn't possible from what I've been reading elsewhere on Stackoverflow.
Take a look at Bluetooth Low Energy.

Here is another example,

You might also want to look into GameKit and peer-to-peer connectivity there.
I can't tell you anything about it, but you might try looking at iOS 7. If that's an option, I'd take a look. Can't talk about what it is because of NDA though.
Depending on what you need to communicate, you could try checking out this project, which lets you share arrays of strings between iOS devices over Bluetooth LE.
You don't need to "pair" the devices and it can still communicate while the app is in the background. SimpleShare
Hope it helps!
From the documentation of MultipeerGroupChat:
MultipeerGroupChat sample application utilizes the Multipeer Connectivity framework to enable nearby users to discover, connected, and send data between each other. This sample simulates a simple chat interface where up to 8 devices can connect with each other and send text messages or images to each other. Here you will learn how to bring up framework UI for discovery and connections and also how to monitor session state, listen for incoming data and resources, and send data and resources.
This is an excellent example at developer.apple.com here is the link
https://developer.apple.com/library/ios/samplecode/MultipeerGroupChat/Introduction/Intro.html
Also this tutorial from Ralf Ebert demonstrates how to use Multipeer Connectivity framework for peer communication should help you.

Is there any frameworks for find out the surrounding networks and network strength. Please tell me if it is possible or not in ios 4/5/6. Either is there any sample code for this.
For example i am using in iPhone Airtel network. Based on Airtel network i need to find what are other networks in that particular area and what is the signal strength of that network.
Thanks in advance.
As far as i know this cant be done using public API's. You need to use private API's check thi s out MobileApple80211 framework.
Yes it is possible. In fact there is an awesome 3rd Party library for this called iPhone-Wireless
This provides you -
view the wireless networks in your area.
signal strength of each network.
For iOS 5 you'll need a jailbroken iPhone. Guvener Gokce has a very educational blog post on this: iPhone Wireless Scanner iOS5
Hope this helps but keep in mind that this library uses private API's and your app might get rejected from app store.

I have found a few samples on how to use GameKit for bluetooth communication and even accessing bluetooth functionality using native code but no example on how to use the MonoTouch.CoreBluetooth namespace.
Seems a shame using hacks when the full implementation is just waiting to be used.
Can anyone please share a sample or source (a link to a book would work as well) for the new MonoTouch.CoreBluetooth.
CoreBluetooth is just for communicating with devices that utilise the Bluetooth Low Energy Profile, such as watches, heart rate monitors etc.. It is not possible to use any other profiles with CoreBluetooth, so not possible to connect to another phone, a computer etc...
(Although given the name, I hope in future apple will provide lower level access to bluetooth comms in this framework)
Up until iOS5 CFNetwork was all you had to use to be able to find and connect to devices using both WiFi and Bluetooth, but as of iOS5 Apple decided to restrict CFNetowrk to only find and comunicate with services over WiFi (Technical Q&A QA1753) So I was left with a huge amount of code that I cant use no more and must now focus on C based implementation using C based API to rewrite bluetooth communication over bonjour.
Since this is the low level type of code, and I am not a deep C diver, I would like to know if there are examples or even better sample code of such communication, where you have a Server class and Browser class. It will take me ages to write it my self, so if you know any of those samples I would greatly appreciate it.
You should check out to see if Apple GameKit would fit your needs.
GameKit handles pairing Bluetooth devices. You implement you own pairing of WiFi connected devices. GameKit handles the rest of the communication.
I was facing similar problems wanting to use both WiFi and Bluetooth. GameKit worked very well for me. Reduced my networking code by more than half.
Apple has good sample code on their developer site.
First and foremost,
I am looking for a resource to use Private API's.
this is an enterprise application and will never go to the app store
I need to take as much configuration out of the users hands as possible.
That being said, I have a device that an ipad will be connected to and communicate with via an adhoc wifi network supplied by the device. the ipad connects to this device and sends raw data to it via socket connections. I also need to connect to the internet for data syncing.
80% of the time, the ipad will be connected to this adhoc wifi device. Management software on the ipad does not allow the user to adjust wifi settings so I am trying to make sure I am connected to my device without limiting my server syncing. I know I can determine the connection using apples Reachability class, this is not what i am looking for. I need to use BOTH 3g AND wifi.
Is there a way to enforce this in code? Or is there a resource for the private API's that I can look at to find a way?
This will be in iOS 5 and the most preferable method would be to just route my http requests via some private api method to use 3G and let the socket requests use wifi to the adhoc device.
code samples would be awesome, links / class names to research would be very much appreciated.
and once again this is not going into the app store, it is an enterprise app
the resolution i found was to assign an ip in the privately assigned ip range the ipad uses (169.254.x.x) to the adhoc device then let the ipad determine an ip. Then see if i can open a socket connection to the device (to determine if its available) and then issue a print.
Going this route, i am still able to use 3g data as well as communicate with the device via wifi.
