RIL and IMEI fixed!
So after lots and lots of different "fixes" I've finally fixed IMEI and RIL on CM9. The most important part of it is that USB mass storage and Audio are not broken, and we can have our RIL fully working! Expect new release soon with some minor changes!
Remember that microphone is not working, and front speakers either, so it is unable to make a call at the moment!
