I recently Jailbroke my Verizon iPhone with GreenPois0n and it worked great. However, I'm now thinking ahead to iOS 4.3. Assuming there's an untethered jailbreak available, I will certainly want to upgrade. But since this is my first time Jailbreaking, I'm not sure what happens when you upgrade firmware? I believe you lose your Jailbreak and Cydia apps, right?
So what's the correct procedure for upgrading for a newbie like me?
1) Upgrade firmware to 4.3 using iTunes
2) Re-Jailbreak using whatever method is available
3) Re-install Cydia
4) Re-install all of my Cydia apps
