dun think u can get it. but seriously no worth it to get it now also. A9 chip inside is rather old. after ios 13 should have no more update.

IMO I'd rather have a used iphone rather than a refurbished set, unless it came from apple. 3rd party refurbished set, may not contain the original parts etc.

should be. highly possible. becos A9 until iOS 13 has 5 iOS versions supported till now.

the only model of iphone has 6 iOS versions supported is iphone 5s, the rest all has only 5 times.

yes, that's one it is considered one year older than iphone 7 which their launch dates difference is merely half a year.

Correct. No point to get se now even u can find one.

to be frank, apple is considered quite sincere in this area. despite the premium paid, one can easily use an iphone for more than 5 years. it is actually worth every single cent that you have paid for the phone.

best thing is a phone, u can at least 5 years of software upgrade, it is incredible.

comparing to any android, you may not even get more than two times of software upgrade and the phone may not even last more than 2 to 3 years. 

of course can. ios13 is the 5th ios version that A9 chip supports.

Yes. Certainly can for two to three years also no prob.

I am still using iPhone 6 Plus 64gb. 😀
