Thank you very much!

"i have been to" means that you have visited the country before in the the past, while "i have been in" is used when you are talking about a particular country you need to make a definite statement about. e.g i have been to London. therefore, the two words mean the same thing.

Someone talking about his or her travels might say "I've been to London" before. Someone who already lives near London might say "I've been in London before", but this second phrase is not the way it is normally expressed. http://www.italki.com/answers/question/157472.htm

I have been to France. I have been to Egypt. to indicates reaching a place or travelling there. in indicated immersion or being surrounded by something. So you might say, while I was in Egypt . You would say "I was in the city" but you would not say "I was to the city" as that makes no sense.
