The issue is expected behaviour with jailbroken devices, as most modern jailbreaks like evasi0n and Pangu disable OTA updates to ensure jailbreakers don’t accidentally install the update.
So the only option jailbreakers have is that you have to update your device using i Tunes.
Tai G provides an i OS 8.4 and 8.3 untethered jailbreak.
Check @Pangu Team, @taig_jailbreak, @saurik, and /r/jailbreak for news and updates. If you are telling on an unlock you will have to use snowbreeze to create a custom IPSW to restore to.
If you’ve a jailbroken i Phone, i Pad or i Pod touch, and trying to update it to i OS 8 using OTA update, then you are probably seeing the “Checking for Update” screen as you can see above.
If it does, just have Apple unlock it again.i'm using straight talk service please help.
I was so excited to get the phone and i feel like I can't even use it ------------- Owning a Iphone 3G or Iphone 3GS in 2014 is like owning a 1985 VCR player… It still can be used, but youre gonna have a very very very very very very…
You will need to re-jailbreak and re-hack unlock via cydia app…
If you unlocked via subsidt device unlock code via Apple, then it will not remove the unlock.
