Apple Releases iOS 6.1.2 To Fix Exchange Calendar Bug [Updatedx9]


As expected, Apple has just released iOS 6.1.2 (build 10B147) for iPhone, iPad and iPod touch.

It fixes the Exchange Calendar bug that was reported few days back.

From the release notes:

Fixes an Exchange calendar bug that could result in increased network activity and reduced battery life

Jailbreakers should avoid upgrading your iOS device to iOS 6.1.2, until the evad3rs dev team confirm it is safe to do so. Jailbreakers should also take a backup of the SHSB blobs for iOS 6.1 or iOS 6.1.1 using TinyUmbrella before Apple stops signing iOS 6.1 and iOS 6.1.1 firmware file, if you haven’t jailbroken your iOS device with evasi0n yet.

    can anyone confirm if they blocked the evasi0n jailbreak with this update?

      Do you want to do the honours?

        I would have loved to but my laptop is in for repairs :(

    • Sebastian Rasch

      Can’t confirm but since this was a very urgent update to fix a flaw, I’m pretty sure they didn’t have time to block anything.

    Why’d they stop signing 6.1.1 so fast?? getting crafty. Reminds me of the cat and mouse game that sony would play with us, back in the PSP days..

    • dt56

      It could be because they simply don’t want anybody using 6.1/6.1.1 due to the exchange bug. What worries me is that there are a number of exploits used in the evasi0n jb and it seems that if they just block one, everything stops working. Hopefully, if this is the case, then the evad3rs can find another.

      Keeping my fingers crossed!!!

    Anyone else running into issues updating to IOS 6.1.2. Getting a lot of errors, 21, 6, not eligible for build request, stuck in plug into itunes logo. I did tried to update thru itunes but it stops when you get the apple with space below, it never fills up & stops after awhile & gives the error. Never had this issue. Had to use tiny umbrella to get out of recovery. It worked once but the next 4 times didn’t work. This is frustrating. I need this fix since my exchange emails are very important & ever since 6.1 haven’t been able to use them. Wait a pain.

      can’t update at all… keep getting the search for update message, but nothing else moves…

      Finally able to update to IOS 6.1.2 after 8 or more tries it took. That was as hard as when I couldn’t use absinthe but I’m good now. Off to jailbreak.

  • jaybeans821

    Apple probably didnt touch on the JailBreak because they are taking their time to put up a tough wall to defend against the evaders…

    Now I’m getting an error that say’s cannot connect to itunes store & I just did a back-up & removed items from my phone. Really strange things going on with this update. It started with my phone showing 2 apps available for updates but it will not let me see what the 2 updates are it just has blank screen. I can select other tabs & the info shows. Maybe I will have to restore again. I still haven’t done the jailbreak so it has something to do with apple/ios 6.1.2 not a jailbreak issue. I’m guessing of course not a technical person at all but these updates & jailbreaks have been pretty simple to complete. SMH
