Not all of them are. We did the lineup for the 4, 4S, 5 and the first 2 iPads because we could due to work commitments. Now I don't bother, but they were fun times and I did enjoy them.These people are iPhone resellers. They are waiting to buy phones at full price without carrier activation (which you can not reserve online), so they can ship them to their home country. They are paid handsomely as a reward for getting as many phones as they possibly can on launch day.
Waiting in line and not getting the phone you wanted now? Wow that would suck if you wanted a plus model tomorrow and they don't have them. I guess we will find out in about 12 hours when Apple in Australia open their doors
