Can I use pinterest on my iphone without the app?

I don't like the pinterest app at all. So I deleted it. I figured I'd just use the full website.
But, whenever I try to go to pinterest.com, the App Store opens and wants me to download the app.
It just won't give me another option. It's frustrating. How can I just go to the website without the stupid app?

Alternative to iPhone. Are there any good ones?

The functionality on the iPhone 4 is very good. I've noticed none of the cheaper smartphones can compare to it. But up the price scale, is there a competitor which can give the same satisfying experience. I'm thinking of the most expensive HTC, samsung or blackberry etc. I don't know because I've never used one of those phones and I don't keep abreast of these things. The reason is I want to dispose of my iPhone, because, nice as it is, I can't stand its faults. So please enlighten me… Is there a phone out there that can match it?
