How to update iPhone without wifi?
I need to update iPhone to get important security updates. I do not have access to a wifi connection, and even when I do, cellular is much more performant: in Australia, about 20 times better download on 5G than on broadband (250 Mbps vs ~25 Mbps).
How an I work around Apple's archaic restriction that makes updating an iPhone impossible without wifi?
Solution 1:
Try with iTunes with a laptop (where you make an Access Point from your phone).
So PC is connected via 5G via phone, and then you download the update and install it via iTunes.
