I originally ordered a 12, but cancelled it. I ordered a case for it, so I have a useless case that I can either send back or buy a 12 for it.I wouldn’t recommend the 11 simply as two years old is just a bit too old to buy the device new. If you keep the phone for a number of years, the extra to get the 13 doesn’t work out as very much, not to mention the fact it’ll be worth more if you sell it later
I guess if the upfront cost is an issue then the 12 is a halfway house in terms of cost. It’s also a bigger upgrade from an 11 than the 13 is from the 12
