Yea, the cell radio doesn't seem too stable. I always blamed it on CDMA not being optimized, but I've seen some GSM guys report radio issues as well. So there may be hope it'll get fixed eventually, but I don't know of anyone looking into it currently.

We'd probably need a logcat or something from when this happens. I've only had the speakerphone issue happen once to me, but I've had reboots and radio cycles galore with calls. I just avoid calls like the plague in Android.
