It will depend when on the manufactured date. If it was recently shipped to the store, say a month ago, most likely you will have a previous software version. But even those that sent theirs in for repairs, some of them came back with 4.3, others didn't. If you are getting it brand new unopened from a store or from Verizon, there is a sticker on the box. The software version is on there. For example the guy I got mine from is pretty much brand new, the box says 1.610.10 but the guy must have wiped it and updated it to 4.3 before he shipped it out.
Before swiping your card look at the software version on the sticker of the box. If it starts with 2.10 then you don't want that one.
