I do not believe that Israel would willing divide Jerusalem. If such a division did occur, because of some peace treaty negotiations, the city would likely be divided between West Jerusalem (to Israel) and East Jerusalem (to Palestine) and the Old City of Jerusalem would be under some sort of Israeli or international aegis. After the failure of the Taba Summit Agreement, the Israeli populace would not get behind a Palestinian-controlled Old City.

The best place to experience Judaism in Jerusalem today for beginners would be Aish and its located in the Old City of Jerusalem. Slightly more advanced would be Ohr Sameach. Both are great places with great people and Rabbis.
