It has been years ago I used it as my phone. It was very expensive. So when the business folded, I stopped using it and got a cheap phone.
But it still works. Kind of sort of. I can get Internet via my witless. But now it is having a hard time. Maybe I got a virus? How can I reset the iPhone 4?
My knowledge of Apple stuff is very limited.
( I once had an Apple ][ a long time ago. )
Any ideas?
