Apple released iOS 7.0.6 yesterday which includes a patch for SSL connection verification. Evasi0n7 jailbreaking tool didn’t support the new beta so an unofficial version was released to jailbreak iOS 7.0.6. However, evad3rs just released an updated evasi0n7 tool that includes support for iOS 7.0.6. For upgrading to iOS 7.0.6 backup your device and restore in iTunes, then jailbreak (and restore your backup). DO NOT USE OTA UPDATE.
To learn how to jailbreak your iOS device using iOS 7.0.6 you can follow this tutorial ( links for the new evasi0n7 tool included )
