Hi, I'm after an iPhone 7 or later model, in working condition to use as a GPS on my motorbike.

I was talking with someone recently who came off his bike and spent half an hour (bruised but able bodied, in the daylight) searching for his phone, which had been 'securely' mounted on his handlebars. If seriously injured and needing to find his phone before calling for help, he'd have been in serious trouble, and worse at night. So, I've come to think that my trusty, every day SE iphone should probably stay in my pocket.

Thanks in advance, R

iPhone 7 or later (Sydney)
