Ok, and more importantly, 2G should work outside U.S., too, good.

2 cores and more importantly 1GB of RAM. Nice. OTOH, I'm avoiding N950
due to its crazy "security" system and this one is even worse. RAM and
CPUs are nice, but phone calls are what is important for me. And
battery charging, I guess. Serial port on the USB connector _is_ nice,
OTOH. 

Anyway, good luck, and thanks for the pointers. I will get Droid 4 if
it is easy. But I guess I'll stick to N900 for now. I want something
that can do voice calls.

Best regards,
