Apple seeded iOS 4.3.5 recently to fix Vulnerability Issues with Certificate Management. This update comes within 10 days of Apple’s last iOS update 4.3.4.
Now, for GEVEY Sim unlockers, here’s a good news. GEVEY sim works on iOS 4.3.4 as well as 4.3.5. Apple hasn’t updated iOS 4.3.5’s baseband and it’s still 04.10.01. Users those who don’t rely on jailbreak can update to iOS 4.3.5 and still use GEVEY Sim, GEVEY Pro & GEVEY Supreme. GEVEY Ultra will also work after you jailbreak iOS 4.3.5 with redsn0w.
Here are some screenshots:
The procedure for using GEVEY Sim, GEVEY Pro & GEVEY Supreme remain the same. Just dial 112 and turn the Airplane mode on and off. If you’ve any questions, feel free to ask below!
