What is the best website to jailbreak my iphone?

I tried jailbreaking my phone last night and it froze my phone on the apple logo so I had to restore it. Anyone know a website that actually works & is safe? I have the iphone 4 and ios 7.

I accidentally landed on this page and followed this tutorial for my iPhone 5S on iOS 7 and it worked for me and also provide the latest compatible Cydia Apps and Tweaks.

Websites don't jailbreak iPhones. You download the software available from the site & use that to jailbreak.
