I just received my new iPod Touch 4G from Amazon. Before I get too attached to it or load up too much personal stuff, I'd like to test it, to make sure I didn't get a lemon. The sooner I find out if I need to send it back for a replacement, the better. I did the exact same thing when I bought my 27" iMac earlier this year (fortunately, my iMac was perfect ). So. What should I look for, and what should I test? Based partially on what I read here, I think I should test this so far: 1)Dead pixels - Is there a best way to test this? (for the iMac there's a little app that does the test). 2)Uneven screen illumination - I suppose I should just eyeball it, once I get to a uniform color screen... 3)Light leaks around the various buttons and top of screen - I'd guess going into a dark room and turning the brightness all the way and looking at it from the side etc. 4)Camera doesn't focus properly (misaligned) - take a photo of something like bar codes, and then enlarge it and see if it is in focus Testing the battery is not immediately practical, but down the road... Anyhow, anything else I should be looking for? Thanks!
