This tip will help you learn how to upgrade from an existing jailbreak. If you're currently jailbroken on an older firmware version and want to update, it can sometimes be a bit trickier than just restoring in iTunes and backing up. In most cases, it's always best to start with a clean slate and not restore from a jailbroken backup (with a few exceptions). Luckily there are a couple apps and tweaks out there that make the process not as daunting. Hit the break for some suggestions and a walk-through!
Most jailbreakers will agree that not restoring from a previously jailbroken backup is the best way to upgrade. For the most part, I'd have to agree. The only exception I see to this rule is if you have to restore (not upgrade). For example, I recently had to swap my iPhone out. I was already running on iOS 4.3.3 jailbroken. After I swapped my phone, I just restored from a backup. I have never typically seen ill results from restoring on the same firmware version. It gets a bit more hairy when you are dealing with different firmware versions and different jailbreak utilities. Whenever you are upgrading to a newer firmware version, always start fresh if you can.
Re-jailbreaking is definitely not the easiest process in the world but a clean start is always best. I've found bad jailbreak bits can come over when restoring from a previously jailbroken device. So doing it right the first time can save you a lot of headaches in the long run. If you've done this process or are just trying it for the first time, let us know your experiences in the comments. And if you have issues, let us know in our TiPb jailbreak forums!
