We're keen to acquire an iPhone for testing purposes.  As it is simply for testing mobile device management platforms, we're looking to spend as little as possible while still having a couple of years useful life remaining (i.e. will run the current version of iOS for 2 years minimum).  Some damage is probably fine.  Desired specs are:

• 6" or larger screen in good working condition.  A minor crack in the display is fine as long as 100% of the touch screen works.
• Back glass condition not relevant.  If broken, we can put the phone in a case.
• Working cameras.  Working but damaged is fine.  We just need to be able to test enabling/disabling the cameras by policy.
• iPhone 12 or newer so we get 2+ years use out of it.
• Battery condition is not terribly relevant as it will be plugged in for majority of the rest of its life with us.

Not in a massive hurry, so if you free up a phone in the next 1-2 months please check back here.  :)
