Experimenting with Bluetooth code... Problems

Using a HTC Desire running cyanogenmod 7.03 to debug some new android bluetooth code. Im using the BluetoothChat project to just use a button to turn on/off Bluetooth initially...

Everytime i add something that affects the BluetoothAdapter the application closes

EgmBluetoothAdapter = BluetoothAdapter.getDefaultAdapter(); if (!mBluetoothAdapter.isEnabled()) Causes my application to close

Here's my code in full from JocActivity.java - my main and only java file: A lot of this is commented out, as i have been trying different things, but its basically set up so that when the button is pressed, the the Bluetoothadapter is queried. im trying to get Logcat working but its not telling me much yet :( Any tips? Im thinking it might bew that my SDK is 2.2 compliant, but my phone is 2.3.3 Im downloading 2.3.3 but its slowwwwww here :(

You probably need to add bluetooth permission to your AndroidManifest.xml. But please, check your stacktrace in logcat/ddms.
