Hi all My iPhone has been malfunctioning for the past month or so, particularly the touch-screen receiving touch points at the wrong location, resulting in calls I didn't want to make, areas of the web page I didn't want to view, etc. etc. Additionally, sometimes the screen will go blank when I try to unlock the phone, even resulting in a shutdown and restart occasionally. These issues occur almost daily, but they don't happen enough for me to be able to replicate the issue without luck on my side. They happen at the worst of times. So I took it into the Regents Street (London) Apple Store to get a replacement - I had an appointment with the Genius Bar. As I suspected, they were unable to replicate the issue, and therefore unable to replace it. This leaves me in quite a predicament. I have an unreliable, malfunctioning iPhone, that doesn't malfunction quite enough for me to be able to replicate the issue! I was told to go to the Apple site, depot.info.apple.com, but the issue I'm having wasn't even on the limited select box of options! I selected a random issue (AC adapter problem), and then couldn't even describe my issue clearly in the text box, due to a 250 character limit! So I came up with an insufficient description, submitted it, only to discover I need a credit card!! I don't have one, nor do I want one, and I'm not getting one. So here I am, with a malfunctioning iPhone that Apple will not replace! I've done everything I can to try and resolve this issue - reinstalled the firmware, restarted it, etc., but to no avail. So what am I to do? I'm a good Apple customer - I've spent a couple of thousand pounds there in the past couple of years, and yet right now I don't feel like Apple are on my side. I require a replacement - do any of you have any tips? Or, are there any Apple employees here that might be able to help me? Thanks.
