I've just downloaded an app from the App Store called System Status which gives you detailed information about the iPhone it's installed on.
One of the features provides a system log which allows you to see the network info when you roam from one BSSID to another.
My question is how did they do this?
I have searched everywhere and the only way I have found requires the use of private APIs. I am assuming that since this app is live on the App Store there is a legal way to obtain the information.
After some deeper digging I think that they got the information from the Apple Status Log, more details are available via these links:

I am working on an app that needs to add a wifi network (i.e., SSID and password) to the list of known ones of the mobile phone, so that it connects to that network automatically even when seeing it for the first time.
I already did this on Android, and now I will start working on the iPhone version.
Question: On the iPhone, is it possible to have my app (when it runs for the first time) add a wifi network to the list of known ones of the device, and if so, any hints regarding how to do it?
Thanks a lot.
Unfortunately this is not possible on iOS.
Apple doesn't provide any public APIs to add network SSIDs or passwords.
The most you can do is to enable your app to manage the user's authentication for a public network, (as is done for things like Boingo and The Cloud). In this case, when the user joins a network, instead of a webpage opening to authenticate, your app can launch and provide the authentication - but that is as far as you can go.
We asked for clarification on this point to Apple in the dev forums and were told that it is definitely not possible. (I will try to dig out the link to that post for you when I get more time. Else, search your query on the dev forums and it might show up).
so it would seem that with iOS 6, there may be a way to do this. Boingo appear to allow a user to turn on "Auto Login" and it will login/authenticate against the access point without the user interacting/authenticating manually (I haven't tried it myself though). Is there new API calls in iOS 6 that now allows this? See this article.
Is it possible on iPhone to create a data connection by specifying the SSID of the network?
Is it possible from application to check the signal/availability of the network with specified SSID?

What you're trying to do is sadly not possible without the usage of private (undocumented) API-s.
Hopefully Apple will provide this kind of functionality (with users permition) though i don't think this is bound to happen soon.
If you want to research this topic further the first place to check would be iphone-wireless - the home of Stumbler which shows a nice usage of MobileApple80211.
I am developing an application where I need to know some of my iphone system information such as the cpu speed and above the list of processes in memory and the system log.
I have seen on AppleStore that there are some apps (Apple-approved) that display the data (Ex JustSys) then it means that Apple provides tools for information system of this type.
I tried searching on the net but could not find anything. Does anyone know how to get this info?
thanks
You should look at below link. Might be helpful for you

i want to create a application which sync my iPhone contacts to my server and vice-versa.
i read a article on google Get Google Sync on your phone . i want to this type of feature which directly update the contact without user interaction (however one time setting is desired).
any body have idea how the google sync work .
Please advice me that how can i achieve this task. any suggestion and link is greatly appreciated
I think it's important to separate the two overlapping approaches in your question.
Firstly, Google Sync is essentially a way to use Microsoft Exchange protocols and to setup a Mail / Contact / Calendar profile on an iPhone. The iPhone OS supports this feature, not an iPhone App in the App Store. Google Sync leverages this fundamental capability of the phone by exposing the data (mail, contacts, calendars) via these known protocols. If you want to expose data in this way to your users, setup a Microsoft Exchange server and ask questions on serverfault.
Secondly, there are iPhone apps. iPhone apps sold in the app store are not currently allowed to run in the background. This means you can't emulate functionality like iTunes or Mail where your music plays while you are browsing the web, or mail checking is done while you are playing a game of Mini Squadron. If you want this backgrounding capability, file a bug/enhancement with Apple.. However, you can interact with iPhone contacts (Address Book) via the API.. You can also of course "re-invent the wheel" and expose the data however you like via the internet, and consume that data from a custom iPhone App with the one caveat that users would need to actively launch your application to get to this data and it would not be integrated with the built-in iPhone Calendar, Address Book or Mail applications. Some good examples of that are some of the music community apps that have messaging systems built into them. Presumably that is all being done with web services.
EDIT: It is also worth mentioning that should you go the "iPhone App" route, you should at least consider if push notifications are right for you, and if so how you will handle it.
Have you seen the API-Docs?
http://developer.apple.com/iphone/library/documentation/ContactData/Conceptual/AddressBookProgrammingGuideforiPhone/100-Introduction/Introduction.html
Next there is an application I use called Funambol - it is a sync4j Server/Client. They have an open source application to sync contacts on the iPhone. Source is somewhere in their repository, informations here: http://forge.ow2.org/scm/?group_id=96
As slf told you your application must run in foreground. This may limit you.
Good luck & best regards,
Florian
The 3.0 SDK will allow your application to read contact data on the phone.
Web services will allow you to publish that data to your server, and receive updates.
You may also want to use coredata to store a hash of all contact data so you can tell what is new / updated and just send that data to your server.
If you deploy an application through the iTunes app store, what usage information do you get from Apple? Do you only get the number of downloads/sales, and does this differ for free vs. paid apps? Do you get any information regarding how often it is used, crash logs, demographics info, etc? Is the only way to build hooks to your own server to track this information and would such an app even get approved?
I've seen articles such as this one that includes quotes like:
only about 20 percent of users return to use a free app the day after they first download it and by 30 days out, less than five percent are using the app.
Is that based on surveys, or is it data that comes from Apple? There doesn't appear to be much publicly available data except when Apple shows the top applications, but that is just based downloads or ratings, and nothing deeper.
Most of this information comes from companies like Pinch Media and Admob. They supply libraries you can include in you app which inform their servers of events in your app (specifically launch but also other events decided by you).
They use these events to provide aggregate information on iPhone apps. Several reports have been published recently referencing this data.
You only receive usage information if you somehow program the reporting of such information into your app.
Number of Downloads (Sales if a non-free app) and more recently crash logs are the only information you receive from Apple. you do not even receive personal information about WHO is was that bought your app, only that they did.
You won't get usage statistics from Apple, only download and sales statistics. The reporting is slightly different for free apps(as they won't show up in the financial report), but basically the same information is provided.
You can however track usage information on your own by having your application ping a remote server every time the app is accessed. You can use the unique device id to track a specific user. This will be dependent on internet access for the iPhone/iPod Touch.
Apple does give you how many downloads have occurred as well as what countries they are from. If you want more detailed usage statistics you will have to go to a third party solution, or write it yourself.
Unless Apple is secretly sending usage information when an app is opened, I don't see how anyone can get aggregate statistics about the whole app store. When I upload an app, it is in binary format, and it is probably unlikely that anyone adds in their own code to secretly do this.
