evasi0n7 has been updated to v1.0.3 and it now includes an updated Cydia bundle and fixes a problematic issue that could cause a boot loop on the iPad Mini with Retina display. The tool also brings support for iOS 7.1b3 which was previously jailbroken with a modified unofficial evasi0n7 tool.
If you’re already jailbroken there is no reason to re-jailbreak your device using the updated tool. Also, there is no reason to update to iOS 7.1b3. Jailbreakers should make a rule and stay away from any beta updates ( also stay away from that update button when Apple drops any iOS update ).
If you din’t jailbreak your device yet, download evasi0n from the links below and follow this tutorial
