I am thinking about getting an iPhone, i think it would be useful cuz it combines my music,phone, and has a bunch of useful apps like calories counters,agendas,dictionaries,books, ect. Is it worth the 100 bucks or not?

Yes it is really useful, I use mine every day and there are a lot of apps that can also help you organize your classes and homework. The calorie counter I use is www.caloriecounter1.com/ It's a very useful investment because you basically have all the things you need to be successful in one product and it will make you very efficient and organized.
