You have about three weeks to get ready to buy your first Palm Pre. Sprint is also thoroughly preparing for the first sales. The carrier plans special store hours for the first two days. Sprint’s stores will close early at 4:00PM on Friday, June 5 and it will open early in the morning on Saturday, June 6, at 8:00AM. Will Sprint have enough handsets to go around in the first couple of days? As we have told you earlier today other locations like Radio Shack, Best Buy and Walmart will also sell the Pre soon after the official launch. What about you? Do you know where you’re going to wait in the line for the Pre?
