How do I unlock my iPhone 4s running ios 7.0.4?

I work for the Evad3rs team, and we have recently released Evas1on7, which is the jailbreaking tool for iOS 7.

There are many methods of unlocking your iPhone after doing this. Just check around on Google and download the required packages from Cydia.

You can download it here:

CAUTION: If you updated OTA (Over-The-Air through Settings > General > Software Update) and not through your PC or Mac using iTunes, do not use the jailbreak tool yet, because there are problems with system files from iOS 6.1 not being removed properly.

You can read more about this problem from this document I typed a while back.
