I really love the iPhone, Ive had everyone of them since release and I am what people call an apple expert, What kinda stuff would you like to know about it? 
wow, thats cool...what is the new  update?
I'm not sure on the iOS version but apple has always released a ton of mobile operating system updated lately. .
cool...im not too familiar with the updates...
Oh OK, Its crazy that very first iPhone was released way back on June 29, 2007, and to this day have been tons of new hardware in their phones ever since. The iPhone is evolving. 
that is crazy how technology has come to this point
I remember when the iPhone 5 was released back in September 12 of 2012, and that was the first big upgrade the iPhone had in years.
