They could have one special card printed for each type of phone they have in stock. Different cards for 16gb of black and white, plus cards for the 8gb black ones. Then have numbered stickers for up to the number of phones in stock. When the store opens they could go through the line and hand out the cards and let each person pick their desired model. They get a card with a numbered sticker put on it. If you DO NOT get your desired model you can then get into a different line to do an order for store delivery for the one you want. I really want to know whether I get a 16GB before standing in line for 5 hours. They could easily do a chart telling you what time to return for your number. If people want to hang out and wait for their time, the OK, let them. Others can return a few hours later. People who arrive later can still get cards (if there are any left).
