Yes, there is an Answers App for iphone in the apple store
yes jailbreaking your Iphone/Itouch will not ever break the devices. the only difference with jailbroken iphone is that you have access to "Cydia" which is an app store made for apps that are not allowed on the Apple App store. I highley suggest using GreenP0isen.

Yes, you can find your lost iPhone with an iPhone app. However, you must have access to another apple product with the same app to locate your lost iPhone. It's called FindmyiPhone in the app store, and it's free. All you do is make an account. Let's say your iPhone is lost, all you do is sign in with your account with another device with the same app and the app will do the rest. Its quite amazing.
