Okay, so I (briefly) tested BionixCore. It seems to have similar issues to all the other 2.3 rom attempts. In my test, I could make calls going out, which worked perfectly, but would not end after the call was over. I could send a text and have it be received, however it still said "sending..." on my side. I could NOT receive any calls or texts in my test. 3g seemed to be working okay though.
Makes me wonder if this problem isn't actually in the radio/radio driver, but in apps communicating *with* the radio. The radio has shown it can work *when it wants to*, we just need to figure out why it won't receive anything (or if it does, what is ignoring this information).
Just adding my two cents. Need my phone to be a functional phone though, so I'm flashing away for now. Defiantly interested in seeing how this progresses though. Reflashing makes me sad because this rom looks so awesome. My upgrade isn't until June, so let's have a working 2.3 radio just in time for me to switch. XD
