As everyone knowns as the iPHone 4s is the latest iPhone. The iPHone sales increased 128 percent the last quarter of 2011. When it first came out, a lot of people were disappointed because they were expecting the iPhone 5, but then, a lot of people bought this phone. The sells increased so much, and the sell in other companies shrinker, like in Nokia. The shares of NOkia in the last quarter shrank by 8.2 percent.Apple sold 37 million phones in the fourth quarter, it is very impressing that this happened but I expect that they are going to sell even more.
