You know what, F*ck Apple!
I have been a loyal customer of Apple and purchased several of their products.
I am sick and tired of their convoluted processes for adapting new purchases.
I just recently purchased a new iPhone 5 to replace my 4s. And have had to replace my laptop after dropping the last one accidentally.
It has taken me hours of frustration to finally figure out how to transfer my iTunes and back-up my old phone. I am so ****** off. I too followed the directions on the support page and spent ages trying to figure out how to find the 'store' menu and 'authorise my computer.'
That's because it is hidden away in the least obvious place you can imagine. I had to trawl the message boards to to finally find the answer.
I can only come to the conclusion that Apple does not want to help you transfer and update your old devices. They want you to give up due to the difficutly and start anew.
Well f*ck you Apple. Look after your loyal customers. Make things more user friendly. Make your instructions clear on how to do things.
