How To Fix SSL Vulnerability For iOS < 4.3.5 By ISSLFIX (Cydia Tweak)

After Jailbreakme 3.0 was released for iPad 2 users, not soon but after a week or two Apple released an update to fix the iPad 2 Jailbreak with the software update of iOS 4.3.4. This update only fixed Comex exploit and no major changes were made. Soon after the release of iOS 4.3.4 Apple released iOS 4.3.5 which fixed the SSL vulnerability known as CVE-2011-0228. This security update was left by Apple and they fixed in their iOS 4.3.5.
