Try the Ars Technica review.
After using the iphone, I think this review is actually quite a bit biased.
The iphone is just now catching up to the S3 and besides things like LTE and a speed boost, it's still has the same feel as the 4s. I guess if you have all apple products, and you have an itch to upgrade; go for it. However, if you really want some quality, wait it out. The Nokia looks like it might be a game changer for Windows. Also, with the iphone 5 still comparable to the S3, you'll definitely get a better phone by waiting for the next big Android to come out.
And as for the new headphones I was looking forward to: The earpods aren't anything special. They don't fit any better than regular earbuds and the sound quality is just what you'd expect from cheap headphones. If anything it might not even fit right in a lot of people's ears, as they're not adjustable in any way.
