her sim worked in this phone just last week when it was the previous build (stock GB). I know the IMEI is intact, and it did work with my SIM on CM9. Because she's about 400km away from me I wasn't able to try it on CM9 & her SIM before sending it back, so I had to improvise. Like I said, the phone number is detected in the phone status menu when her SIM is inserted, just no signal. I believe APN settings should not affect getting a signal, they should just affect getting data, is this correct?
