There is no permanent damage, apparently the phone will get back to life from 24hrs to 1 Week... iFixit did a test in this video.

Also, what is it with people keep making this x-gate stuff everytime somethings comes up, rather annoying... can't you just wait until you or anyone do a proper research and confirm such a problem worth having an x-gate issue? geez.

Just to be clear, this tread is meant to be a parody of the whole "-gate" thing. While it appears that exposure to helium can actually disable Apple devices, it is something that would only ever happen in a deliberate situation like the iFixit video, or a 1-in-a-million freak accident like the gas leak at the medical facility.
 
You'll be fine as long as you don't work in hospitals or go to parties that have balloons.

Big question, though, is why Apple chose to use MEMS oscillator with known drawbacks vs proven crystal oscillators.

The processor in a modern, high volume device typically has its main clock driven by what's known as a MEMS oscillator. These are barely visible mechanical systems that resonate at some designed frequency, and include packaging to convert this resonance into a useful electrical clock signal. These devices are extraordinarily cheap ways to produce a steady clock, but they have a number of drawbacks.
