Hi all, first time poster here. Anyone have any thoughts on purchasing an iPhone 7 in 2019? I had been using an iPhone 6S for almost 4 years, but unfortunately, that phone is no longer available for me to use. My budget will allow me to purchase an iPhone 7 with 128 gb memory from a friend, probably nothing more than that. How many years could the iPhone 7 still possibly receive iOS updates? I was hoping to at least be able to get iOS updates for 2 cycles (this year and next at least). Is it still worth purchasing in 2019, given that it's a 3 year old phone? Any input on my query would be very much appreciated!
