Answer 1

I've searched through all the relevant bits of the SDK and there is nothing. And as you know, if it's not in the SDK and you use it your app will not get approved.

Answer 2

I think you can use another way instead. For example you can post a request. Calculate the time when you get the respond.

Maybe you post a request to http://stackoverflow.com And you get the respond in 1.0s, assign the wifi is very strong. In 5.0s,assign the wifi is weak.

Maybe the way is not exact but is useful. sorry for my poor English:)
