I can upgrade today to either one and t mobile lowered the 6s plus by 100$. Its still fast and has a headphone jack and im thinking that would be the better deal the only thing i couldn't do is brag about having the latest iphone

Which should i buy sisters?

Yes

Yes

get the 7 dude

IMO no. If it was a 6+ then yes.

Hell no! The difference aren't important at all. Like if you take care of your phone you shouldn't be worried about waterproofing/cracks etc. My 6 plus is in perfect condition. I'll be sticking with it until I absolutely need a new phone.
Apparently a huge update is coming for the 10 anicerwey of the iPhone, which is next year.

This update is purely to make more money.

No, unless that $100 is crucial to your existence.

No. Wait for tha 7s is that's tha case

Yes. I upgraded from the 6s Plus to the 7 Plus. Completely worth it.

No its a downgrade.

The 7 is amazing. It's very powerful, it out performed the iMac in speed tests. Don't worry about the headphone jack because it comes with an adapter so you can keep using your old headphones.

The display is also a big upgrade as is the camera.

6s Plus>

No. The 7 is like twice as fast performance wise. So no.

How fast ya'll heuxs need a phone to go, anyway?

No, using a headphone adapter would be annoying af. I'm hoping the 6s will go down in price

Over the 6 yes! If you already have a 6 wait till the 8

Personally I think I might wait until next year to upgrade from my 5C.

I also don't have a steady source of income (college student), so...

This.
