It is necessary to look at the serial number printed on a box, you need to find numbers after 7v7 and 7s7: if there will be numbers 38 and lower, you can buy this iPhone - probability that this phone will have 1.0.2 firmware or lower is very high; if there will be numbers from 40 and higher, the probability of 1.1.1 firmware is very high.

I can say this does work. I picked out 5 iphones from the apple store yesterday.

Thanks

Thanks for sharing.

Haha, the guy at the apple store won't let me look at the phones but he looked for me. (Cambridge Galleria). The other apple store let me look at like 5 iPhones. (North Shore Mall).

What store is this? They let you have a look at the box before purchase?
