When will the iphone X get back in stock?

I live in NYC and i'm trying to get an iphone x but they are sold out everywhere.
I have to leave the country for 2 month in november 22nd.

Do you think by then i could get the iphone x? (I'm leaving in exactly 2 weeks).

There's a yellow wax like substance on my iphone 6?

I had my phone on the charger for around 45 minutes and when I unplugged it I noticed a yellow wax like substance on the top right corner. I tried to smell it and it almost smelled hot? If that even makes sense? It was just that part of the phone that smelled too.

For some reason I can't view comments on Facebook app on iPhone 6s
