Purchased my iPhone 5 (32 GB, White) in early November last year, had absolutely no problems with it, loved using it. Came to about 2 weeks ago and the lock button started playing up, only slightly, but this worsened as it always does and it eventually became unusable around last weekend so I booked into a genius appointment on Monday. Went to the appointment, got my phone replaced no questions asked. And now I sit here 3 days later with a phone that I want to throw against a wall. This time, the home button has stopped working all together. This wasn't a gradual problem, worked fine one minute and then not at all after. I've got another genius appointment tomorrow for my mac, so going to see what they say tomorrow, will be asking for a refund if they do not replace it. Trekked to my nearest Apple Store 3 times the last week for genius appointments, really not amused! Has anybody else had any problems with the buttons on the iPhone 5 or have I just been unlucky?
