Re: I want to check that my iphone update via ota or itune.
Follow this. One of two things is true: It was updated via OTA or it was updated via iTunes.

If it gets into the boot loop, just DFU and restore. Not only does it clean up the security issue, it moves the phone into the only state it might be jailbroken at a later date.
If it was updated via iTunes, the jailbreak will succeed and you can use tweaks to mitigate the security issue.
Either way, you don't want to remain in the current state. Why would you care which of the two states it is in?
