Should I upgrade to iPhone 5 or 4S?

I currently own an iPhone 3GS. IPhone 5 has not yet arrived where I live, and is (obviously) going to be pricier than the 4S.
I was wondering whether I should wait for the iPhone 5 and invest more money or go with the now cheaper 4S.
Note that LTE is not supported in my country as of now.

Any comment will be apreciated.

No they all the same

4s the i phone 5 is basically the same thing just more expensive

I made this exact same change a couple days ago. Same situation too. I bought the 4S, as the 5 has extras I don't neccessarily need, for an extra 100 euros.

Just get iPhone 4S. IPhone 5 isn't any different.

5 is obviously better, but which you upgrade to is up to you.
