I've just got a Nokia N78 today. The phone is nice, but I'm finding complicated to make many things that in my past Nokia 6300 were very easy. My current problem is the next: When I go to my contacts and press the Call button in one that has mobile and home phones, my phone won't automatically call the mobile number (as it did in my previous Nokias), but will instead ask me which one to call. Is there any way to change this? To set the mobile numbers as default? Thanks.
