Overall:

First during pre-order time - "where got stock a?", "can xxx reseller reliable ar?", "can do EPP?"

then during waiting period - "xxx said delivery today but nowhere been seen?", "still stuck at xxx, status no update"

when some got their phone, it has 2 parts -

1st part: this is for those who planning to buy/still waiting their iphone to arrive:
- "where you bought? still got stock?" "is the xxx discount voucher can be use?", "can someone update me xxx colour still available?"

- "got hissgate a?", "pls confirmed if got hissgate"

2nd part: those who got the phone:

- "hissgate very loud when i put my ear near logo, is it normal?", "wah, why screen so yellowish?"
that's the overall for iphone 7 and 7+ 

did i miss out anything?
