Both my wifes and my G1 has this problem...so I think it is an app. Basically, sometimes (every couple of days), when a phone call comes in, the phone will start to ring and/or vibrate, but I can't answer. eventually we will get a notice of a crash, and ask if we want to force close or wait. I believe it is the phone app. I will pay closer attention next time it happens... has anyone ever seen this, and know what app is causing it? mm0 P.S. Apps we have installed are: SMSPopup, Missed Call, Contact Owner, among others... P.P.S. I am running CM3.6.5, but also had this problem on JF1.51 ADP.
