Pretty bad

The FM tuner is not too bad itself but the whole thing keeps crashing after a few minutes when mutlitasking or even when simply locking the iPhone (using iPhone 4 FW 4.3.1). I get the message saying to connect the iFM hardware... To avoid this, youll need to keep the app awake (with screen on) and therefore drain your battery. This is pretty disapointing as we are also unable to either play games or use Internet while listening to radio. Need a fix please...
