title: iOS wifi scan, signal strength
body: <p>As far as I know it's not possible to scan for hotspots in range and read their bssid and signal strengths. This was possible on iOS 4 by using private APIs and not longer possible on iOS 5 without jailbreak. Even if it were possible, the app would be rejected on the App Store. Is that right?</p>
  
  <p>One company that has an indoor positioning system is claiming they can develop this system in iOS. I know for a fact they are scanning for hotspots and signal strengths and then triangulating the signal on their current Android app.</p>
  
  <p>Are there any alternatives I am missing? Their claiming sounds impossible to me but I would love to hear from the people here. I would like to be ready when they demo (although I am expecting a jailbreak or some kind of mock up)</p>
