Anyone who thinks Apple is removing the 3.5mm jack from the iPhone7 is nuts. Apple isn't the kind of company that would pass out thousands of presents that they know are going to be obsolete in a few months.
That would almost be like Apple continuing to sell an outdated product like an iPad 2 for years after it was well behind the times...
Before people attack this. Please note that Apple has 115,000 employees as if Mid 2015. That's an $11,500,000 in company gift value. Ask yourself if the company you work for doers this or has something of the same value based on quantity.
I remember working for a company years ago that had probably 100 employees. We got $5 gift cards for Christmas. At the end of the day a gift is just that, a gift. Be thankful for what you receive.
