Which color display is accurate? IPhone or laptop?

When I edit photos using Photoshop on my laptop, they seem fine when I upload them to websites like Tumblr. However, when I look them up on my phone, the colors display a higher saturation. It's enough of a difference to make the photo seem jarring. I tried calibrating my laptop, but there's still a fairly significant difference. If anyone can tell me which one is more accurate that would be awesome. It would also be helpful if someone could take a look at the photo (link: http://jenrihames.tumblr.com/post/71885725664) and tell me if it's too saturated or whatnot.

Much appreciated, thanks!

I think it's the laptop that is more accurate. The phone is only processing what its windows can handle. Which means that the phone doesn't always have the best quality for your pictures, videos, or slideshows. Trust me, the same thing happened to me. IT's just what the phone interprets the image to be.
Hope this helped.
