Yes, the iPhone 6 will still be usable in 2021. However, it may not have the latest features or be as up-to-date as newer models.

Yes, the iPhone 6 is still a great phone. It has a lot of features that people like, such as the large screen size and the ability to take great photos.

The iPhone 6S was a great phone when it was released in 2015, and it should still be good in 2021. The hardware is still relatively new, and Apple typically supports its devices for around five years. So the iPhone 6S should have at least a few more years of good use left in it.

To reset an iPhone, you need to hold down the power and home buttons until the phone turns off. Once it’s off, hold down the power button again to turn it back on. You’ll then be prompted to set up your phone like new.

Apple typically supports devices for around 4 years. However, given that the 6s is a newer model, it’s likely that Apple will support it for a bit longer than that.

It depends on your needs and budget. If you’re looking for a phone that will last you a few years, has a lot of features, and doesn’t cost a lot, then the iPhone 6S is a good option. However, if you’re looking for the latest and greatest technology, then you may want to wait for the iPhone 7.

To unlock an iPhone, you need to enter the passcode. If you don’t know the passcode, you can try to restore the device using iTunes.

The iPhone 5s, 6, 6 Plus, 6s, 6s Plus, SE, and 7 will all be supported by Apple in 2021.

The iPhone 6 and 6 Plus have sold the most, with over 200 million units sold.

Apple released iOS 11.2.5 on February 8, 2018. The update includes bug fixes and security improvements.
