I have a rooted LG Optimus V with Cyanogenmod 7.2.0.rc1-backside-iho rom. In a seemingly random manner, incoming calls to the phone do not ring the phone and go directly to voicemail, annoying to no end when my wife is trying to call me. The phone at these times is sleeping, and if I wake the phone up, I see, for a moment on the main screen "no service".. which makes me suspect the phone thinks its in "airplane mode".. This does not happen all the time, just enough to be highly annoying.. When the problem is not occurring, and I wake the phone up, I see "virginmobile" immediately vs "no service"... What's going on here??
