Is there any ways to find out the Wifi Passwords saved on my iPhone / iPad without Jailbreaking the device?
If anyone suggests me it would be very goood :)
Not At All ! Strictly No! You cannot do that in any way on a non-jailbroken device. I think its not even possible on Jailbroken devices as well(Not sure).

I know this is only possible with private API, this is for a jailbreak tweak NOT the AppStore
I am trying to toggle the cellular data option of the iPhone. I have found APIs for Bluetooth, Airplane mode, wifi and GPS, but not for 3G or cellular data.
Where can the API for 3G and cellular be found?

I want to record a demo of my app on the device. For the purpose of recording an in-app demo, is there a framework which can be dropped into an app to record the screen?
Of course this framework would be removed prior to submission to the App Store.
if your device is jailbroken, try this:
I dont know about the quality. If you can also demonstrate your app on iOS Simulator, use any Mac screen video capturing programm and record your screen.
After it, cut your iOS frame out and you are done.

How can we support printer in a iPhone application? I want to print a page from my application. Do I need to code for this in my app or this is a default operation supported by IOS. I am using IOS 4.3 & above.
Look at the Drawing and Printing Guide for iOS.
iOS can only print to "AirPrint" printers of which there aren't many. There are some apps that run on OS X that will "AirPrint enable" any attached printer. I use Printopia (no affiliation other than as a happy user). There are some free ones but I haven't had as much success with them.
It's always a good idea to google your question first :)

I registered to Apple Developer program and paid 99$.
Now I want to test my application on different iPhones. My friend has jailbreak iPhone so i wanted to know if I can use it to test the application.
1. Is that okay with Apple? i mean is it a violation of the developer program terms?
2. Can it undo the jailbreak on the device?
Although this question is off topic, I'll answer it.
yes you can test apps on this device, Apple could know that you are testing on a jailbroke device by it UDID. They will not close your account for that.
No It will not undo the jailbreak unless you upgrade the devices OS via Xcode. Other which it's just like installing any other app.
