I love shopping, I love my iPhone, and I love any application that makes it easier for me to shop on my iPhone. Tommy Hilfiger just released an iPhone app making it unbelievably easy to shop for men, women, and children's clothes, right from your phone.
My favorite part is how closely you can zoom into an item to check it out. One tap adds selected items to your cart and another brings you directly to the check out. The app also allows you to create an account and stores your credit card and shipping info.
Use the app to search by price, category (including sale items!), or size, and browse through top-selling items. And, since there's nothing worse than finding out an item you must have is out of stock, the app allows you to register to receive a push notification when you're able to purchase it. That's one notification I'd be delighted to receive!
