Just wondering if there was a correlation between iPhone batch serial number and quality issues. I'll start. Mine is F2LXXXXXXXXX (Black 32GB) and was flawless out of the box when I bought it yesterday. I also know Sharp and LG are making the screens. Is there any way to correlate the screen manufacturer in the serial? I think most of the panels have been similar so far in terms of tint and quality? http://www.chipmunk.nl/cgi-fast/applemodel.cgi Serial number: F2LXXXXXXXXX Name: iPhone 5 (GSM model: AT&T and Canada) ModelCode: iphone_5 Model Number: MD636 Group1: iPhone Group2: Generation: 7 Machine Model: iPhone5,1 Model introduced: 2012 Production year: 2012 Production week: 38 (September) CPU speed: 1.3GHz Family name: Become a pro user to see this information.
