I don't know if I should wait for the iPhone 7 or just buy the iPhone 6s?

I want an iPhone this year. I have a field trip, and I want a phone to take pictures and also pictures in the summer, which means I would get the 6s, but at the same time I feel like I would want the 7 but it would be weird with no 3.5 headphone jack and all the new tech might crash a lot. I don't know which one to get! Help!

Added (1). my field trip is at the beginning of next month.

Think of the advantages and disadvantages, i have the 6s and I love it, if you wait for the 7 to come out you might not like the 7 and end up buying the 6s anyways but if you want something to take good pictures on in time for your field trip id say get the 7, it also depends on your current phone situation.

Well there's a new rumor on the web that the iPhone 7 might not have the headphone jack removed…

  • Should I wait for the Iphone 8 or just buy the Iphone 7 plus? Why or why not we really still don't know much about the iphone 8 even though it is said to be released a few months from now in September I will primarily be buying the phones for their large harddrive of 256GB But I also like alot of the new features
  • Should I buy the Series 4 Apple Watch, or just wait for the Series 5? I heard the Series 5 may be released around September 2019 but that may be wrong. What I really wanted to ask is this. Do I need to have cellular on my Apple Watch to be able to pair it with my iPhone? It's like $100 more and I just wanna be sure with that amount of money.
  • Should I buy iPhone 5 or I should wait for iPhone 5S? I'm planning to buy the new iPhone 5.It's necessary that i get a phone as soon as possible, so should I buy this current iPhone 5 or should I wait for the 5S? There would be a vast difference between them?
  • Should I buy an IPhone 5 or just wait until the new one comes out? I just got a job at a gas station. It's my first job and I'm 17. My mom pays for my phone but I'm like the only person at my school that still has a Rumour! Supposedly a new IPhone is coming out but I'm not sure. Should I just buy an iPhone 5? Or do you know of any smartphones that are better than the iPhone?
