Talking to the Apple's folk at WWDC, it seemed clear to me that being able to read the RSSI while your application is in the background is something that will go away ...
You should do the work in your device itself, having it monitor the RSSI and sending a notification when required. This will wake-up your application, use less battery and likely more accurate
