    I have mine and my wife's iPhone 5's updated to 6.1.2 and Jailbroken. I know never to update OTA, but I'm not confident my wife won't accidentally update if she is prompted to. With that in mind, I have a few quick questions:

    1) I noticed when Evasi0on was updated shortly after it's initial release, the release notes mentioned "prevent OTA updates". Does this mean if we are already Jailbroken, then the Jailbreak itself will automatically prevent OTA updates? This is the Evasi0n release notes that I was referring to:

    http://www.iphonehacks.com/2013/02/evasi0n-1-2-disables-ota-updates-fixes-timezone-bug.html

    2) Will the phone still prompt us when the next version of iOS is released? Or do we need to install another Jailbreak tweak to prevent that and to ensure we don't accidentally update?

    3) If I understand correctly, with the iPhone 5 there is no way to downgrade, so if we do accidentally update, then we have lost our Jailbreak for good (unless an update for the Jailbreak comes out that works again), right?

    4) If something goes awry on our phones and we need to restore, I assume iTunes will automatically put the newest firmware on the phone, thus also ruining our Jailbreak, right? What if we do a "Erase All Content and Settings" from the phone's Settings menu - does that also update the firmware, or does it just erase the phone, set it as new, but keep the current firmware? In other words, is there a way to erase the phone without updating the firmware so we can stay at 6.1.2 and continue our Jailbreak?

    Thanks!

    Go to Cydia and get the free tweak called SoftwareUpdateKiller and install it. No settings to configure. When the next and subsequent updates are released, you will never know, because no badges or warnings will appear.

    Additionally, install ResetAllKiller. If memory serves, Erase Content and Settings on a JBed device will leave it in an unusable state requiring a DFU restore through iTunes.

    With these two teaks installed, you should be relatively safe from accidental updates from the phone. Just be mindful not to click the update button in iTunes. Many have mindlessly accidentally clicked on even when knowing better. Just be mindful.

    1 & 2) Evasion disables OTA so I don't think you'll get the popup. At the very least it won't let you accidentally upgrade. The button will most likely be grayed out. If you're concerned you can install SoftwareUpdateKiller or No Update (doesn't look like No Update has been updated for iOS6 yet so stay away). As an added measure you can install ResetAllKiller which makes it impossible to tap the reset buttons in settings. But in all honesty, you don't need any of this and it's a waste of "jailbreak resources" to install in my opinion. I am in the camp of only installing what you absolutely need. And these aren't necessary with this jailbreak.

    3) Correct. If you update there will most likely never be a tool to downgrade. There is however a chance that a tool will come out which will allow re-restores after apple stops signing 6.1.2. Only time will tell.

    4) Don't ever use that reset all content button when jailbroken. It will render your device useless and therefore you'll have no choice but to restore to the most current firmware version.

    Good luck!

    Edit: If you have iCleaner installed, you can use it to disable the OTA daemons. But I'm pretty sure evasion already takes care of that. I could be wrong as I never looked into the details on how evasion disables OTA. I just assumed they disable the daemon therefore it prevent the device from ever knowing an update exists and therefore never has the popup alert asking you to install it.

    Anyways, I hope this helps. Everyone else, please let me know if any of this is wrong.

    As mentioned, there is no need to add additional Cydia tweaks to diable OTA...evasi0n by default disables the OTA update service, preventing Apple from nagging you about the update and preventing you from even trying the update manually.

    Much better said. Sometimes a simple "no" suffices haha.

    Wow so you can click on install and it'll install the new firmware? I didn't know this. I'm on 6.1.2 and never bothered to check while on 6.1 or 6.1.1 sice i was only on those for a couple days

    Have you installed the latest evasi0n updates, or jailbroken more recently? It was a patch they made to evasi0n after release. If you jailbroke with the original tool and never installed the updates in Cydia, you'd be able to contact them, but I never got a notice for 6.1.2 and when I go to software update, it just spins its wheels at checking for update.

    Yea that makes much more sense. My assumption was that this is the typical behavior after using the updated evasion which removed OTA.

    Yeah I'm running version 0.4-1 of evasi0n. I had to reset my phone today and now I guess it is working correctly. I get the checking for update now but it's still showing a notification on my settings icon.


    I didn't click on it to test it out so I'm not sure.
