I was holding my wife's identical 8gb iphone 3g next to mine and noticed a few things that caught my attention. 1-My screen is darker than her's. we both have v.5a347 and the same 8gb model. I am aware of the yellow tint associated with the previous firmware 5a345. Oddly hers does appear to be more yellow than mine even though we share the same version # that supposedly corrects this. 2-My phone boots up about 3 seconds slower than her's and runs apps a second or two behind. I have to admit, this does bug me. 3- My sleep button is almost completely flush on the left side making it harder to push in (no joke) where as her's sticks out more all together and is even. I also noticed that my vibrate button is angled off a bit...yes indeed making it difficult to push down. 4-And finally I thought it would be worth mentioning that we both share the famous light leak on the left side of the screen but....mine is worse. Perhaps some useful information: My wife received her iphone a week after I got mine. Makes me wonder if my phone was part of an defective batch at launch. Anyone else having similar results when comparing two iphone 3gs? or have any suggestion?
