I have an iPhone 4 with Version 4.3.3 and Firmware 4.10.01. The iPhone is jailbroken and unlocked via Gevey SIM for T-Mobile. I was wondering if I should be downloading the the 5.0.1 IPSW or 5.1.1. Also, I want to confirm that this tutorial that I found on iClarified still works. - http://iclarified.com/entry/index.php?enid=20516 Thank you.
