I needed to repair an iPhone, and the kit was on sale, so I took advantage of that and ordered it.
Good. I got the tools in the kit, downloaded a guide from iFixit and went through the repair without a hitch. Everything worked correctly.
Yeah, I have some advise.
If you are a computer repairman, the authoritative source for repair guides is iFixit. No other source matches the clarity and accuracy of their guides. If you are handy around electronics at all, you can fix anything with their guides.
I wish the automobile repair business had such a dependable and accurate source for repair guides. Replacing a window crank in my car became a major research and experimental chore.
