Haven't seen the instinct but I love my blackberry curve and wouldn't trade it for anything except maybe a newer blackberry :) Full qwerty keyboard is a must. My husband has the iPhone and hates it. The touchscreen is difficult for me to use when I borrow it to surf the web. I am always pressing the wrong keys. The screen gets all smudgy. The only nice thing about the screen is the size but it's really not necessary. Hope this helps!
