Hi, I am getting so sick of problems with my iPad 2. I got my first one on launch day in the UK and returned it a few days later due to bad backlight bleeding. Thinking that this wasn't a widespread issue, I was disappointed to find my second one had the issue, and my third one too. So, I decided that I would wait for a couple of months with the third iPad 2 I had and replace it after the issues had (hopefully) died down. So today I went and got my 4th iPad 2. No noticeable light bleed, no dead pixels (which 2 of my other 3 had). Happy. However, when wiping down the screen to put a screen guard on it, I noticed that in a number of places (maybe 3 or 4 areas) the dust was not wiping away. So I now have an iPad which is free of all the issues I was plagued with before but with considerable dust under the screen. This dust is only noticeable when the iPad is off and with a bright light on it. So not really a major issue. My only concern is, is if this dust is going to get worse? I have no idea how dust would get in there, so I was wondering if anyone could advise me on whether if I keep this one (which I am more than happy to do so) will the dust gradually get worse as more gets in somewhere, or will the dust that is in there now have been from manufacturing and no more should get in? All I know is that my iPhone has dust under it too after owning it for 2 years and has gotten progressively worse over the years. Yet it doesn't bother me on the iPhone. Sorry for the essay! Any advice, much appreciated.
