I'm just wondering why it is not possible to downgrade the IOS on an iPhone from 6.14 to 6.12 or whatever. I know I can wipe a hard drive clean and install an older OS on a computer, assuming the OS supports the hardware on the computer, and usually it does, within limits or by downloading drivers. So, I guess the question is, why can't you erase what is on the iPhone and reinstall the OS (within reason) you want? Plain English if you can...I only have an M.A. in English lit.
