Answer 2

I was taking a look at the call logs and I noticed that apart from the usual fields in the contents of managedCursor, we have a column "simid" in Dual SIM phones (I checked on Xolo A500s Lite), so as to tag each call in the call log with a SIM. This value is either 1 or 2, most probably denoting SIM1/SIM2.

managedCursor = context.getContentResolver().query(contacts, null, null, null, null);
managedCursor.moveToNext();        
for(int i=0;i<managedCursor.getColumnCount();i++)
{//for dual sim phones
    if(managedCursor.getColumnName(i).toLowerCase().equals("simid"))
        indexSIMID=i;
}

I did not find this column in a single SIM phone (I checked on Xperia L).

So although I don't think this is a foolproof way to check for dual SIM nature, I am posting it here because it could be useful to someone.
