What is different between Model# ME324LL/A and NE297LL/A on iphone 5s silver 16gb?
Which one actually indicates to be the latest model? I received two replacement phones but I need to return them and I want to make sure I kept the latest one.
Please let me know what those model ID means on iphone 5s, one of them is on ios 7.0.6 and the other one is on ios7.0.4
