Can I upgrade my iPhone if it's jailbroken?

Upgrade a old Jailbroken iPhone 3G

  • I'm so unhip, my Jailbroken iPhone 3G is at ver. 2.1 . Unsure how best to make it shiny and cool again. My iPhone 3G has been running the jailbroken 2.1 firmware, as a result of the one and only jailbreak I've done. I don't understand the internals of the process well, let alone the dependencies. Being both a salty, weathered professional in technology, and an utter control-freak, I'm a bit hesitant to just go ahead with some of the instructions I've seen online. Hence, I'm reaching out to the hive mind. When recently I found that the Facebook app for iPhone won't run on 2.1, I realized I finally have to take the step of continuing with the jailbreaking process. So I'd like to upgrade to 2.2.1, or heck maybe even 3.0. However I haven't found much info out there related to upgrading from such an "old" firmware version. I've downloaded QuickPwn 2.2.5-2, along with firmware version "iPhone1,2_2.2.1_5H11_Restore.ipsw" and am ready to give it a go .... once I've gotten some reassurance that I'm not jumping too quickly :-) Subquestion 1: Are there any caveats (esp. related to loss of data - contacts, calendar, etc.) for upgrading from 2.1 directly to 2.2.1 or 3.0, i.e. skipping 2.2 or any other intermediate version? (Note, I am not concerned about the baseband-upgrade caveat; I've no intention of ever unlocking my iphone.) Subquestion 2: What's the role of iTunes in all this? I'm running 8.0.0.xx ; one document I found indicated that 8.2 is necessary, but another said that this would "break" jailbreaking. (Note, I'm running iTunes on Windows, not Mac.) Subquestion 3: Does the jailbreaking process require that I first upgrade to the non-jailbroken version of firmware (using iTunes) and *then* install the jailbroken version? Or can I just upgrade from jailbroken-version-2.1 to jailbroken-version-2.2.1_or_3.0 ? Subquestion 4: Is my understanding correct that, after I've successfully upgraded the iPhone to whichever-version of firmware, that iTunes is then to be used to do a restore of all my data back onto the phone? Thanks in advance for your help, Old Wussy Geezer

iTunes has been sitting on "Updating applications on iPhone..." for several minutes now, still showing "Installing aSleep" without any movement of the progress bar. Decided to slide the slider and stop the synch. Looks like my contacts, calendar, SMS's, etc. are there.

I sort of left this thread dead. Bad armoir! So, things turned out much less bleak that where I'd left off. After the next couple of restores, or synchs, or whatever, I got all my old purchased apps back, along with all my personal data, etc. etc. So the 3.0 upgrade was pretty flawless. I do still need to jailbreak, but it sounds as though that will be much more feasible now that I'm already up to stock 3.0. Man, this thing is *So* much more stable now, than all those long months I was still running 2.1 . I was living in the dark ages.

sourwookie. you can get round that by doing a homescreen layout reset. Settings>>General>>Reset>>Reset Home Screen Layout.

IMPORTANT: If you restore a jailbroken phone and you were running Categories from Cydia, UNINSTALL Categories before you restore. If you don't, your app icons will be invisible, resulting in possible pages of unused desktop.

I'm assuming that my phone is now running the stock 3.0, with a partial restore (no apps yet). Just a note - if you think it didn't restore your apps, check to see if there's a blank page of apps - every iPhone and iPod Touch in my house that was upgraded to 3.0 put an extra blank screen after the Voice Memos app and we initially thought the apps weren't there. Then we scrolled to the right. This happened on both jailbroken and non-jailbroken devices.

A tip for redsn0w. ONLY install cydia. Do not install both Icy and Cydia in the jaulbreak process. It will lead to the problems N2O1138 experienced. Once you have jailbroken and updated cydia you can install Icy from cydia.

You're exactly right armoir, a jailbroken firmware cannot be upgraded to another jailbroken firmware directly (without any Cydia trickery at least). Your best option is to do a complete restore that has no signs of a jailbreak, and then follow the instructions on iClarified. Best of luck!

Thanks, mahoganyslide. I'm assuming that my phone is now running the stock 3.0, with a partial restore (no apps yet). Tomorrow I'll try to go through the jailbreak again. Perhaps this whole excercise has demostrated that it's *not* possible to upgrade straight to a jailbroken 3.0. At least, not from jailbroken 2.1

Uh Oh! The links didn't come through in my last post. Sorry! For jailbreaking: http://www.iclarified.com/entry/index.php?enid=4254 For unlocking: http://blog.iphone-dev.org/post/128573459/ultras-now
