I have a 650, unlocked (old ATT GSM phone that I had unlocked), running 120 ENA and 1.71. The problem I am having is that my phone keeps dropping calls when I am driving. My phone will just drop the call, show no signal strength, then either default to SOS mode or show Full strength and require me to make the call again. I am having, sometimes, up to 3 dropped calls on a single call!

Is there another ROM update of RAM update that can fix this problem? I remember reading about a RAM update that caused the phone to search faster for a signal/tower...anyone have any recomendations?

BTW, Cingular is telling me that there is alot of tower intergration going on and that I should "power cycle" the phone. I have 2 650 and each has the same problem...
