So, the big day came and went, and since then one million iPhone have been sold worldwide. One Million iPhones. That is highly impressive for less than one week of sales. However, even though an impressive number of iPhones has been sold, there have been plenty of difficulties activating the iPhone. Many of these problems were solved over the weekend, but you can be sure that there are plenty still out there with problems. When an item is mass produced to such numbers like the iPhone, there are bound to be problems.
