Kifeas,
First of all I am a proud Cypriot. Your question is irrelevant, who gives a damn about the origin of this city's name? The important thing to remember is that it is now a city occupied by 11 million Turks, it is a city in Turkey, if it was in Greece you could choose to call it whatever you damn like. but it is not in Greece and if you care to look at a world map you will see it is exactly where I said it is, TURKEY. for you to continue calling it Constantinople is nothing but provocation.
btw, anybody who has not been to ISTANBUL should have it in their to do list. It is magical, enjoy.
