Hmm… I managed to brick my iPhone 4 while doing an iOS update.
Took it to Genius Bar, who couldn’t fix it either, and they gave me a replacement phone on the spot. I was well out of warranty but it was a goodwill gesture 😀
Obviously they recognise a fanboi when they see one. 🙂
Does anyone here think a £140 charge is reasonable for the repair?
It is a very reasonable price for a new phone which is what the OP will get. It’s not a reasonably price to pull some pocket fluff out of the button contact – but if you want that done then take it to another shop.
I smashed the back glass on my 4S about 6 months ago and I might be tempted to finally replace it for the bargain price of £25!
Don’t waste your money. A replacement back is less than a tenner and takes roughly 2 minutes to fit, 1:30 of which is looking for your screwdriver.
Undo screws, slide off back, slide new back on, tighten screws. Done.
