The Apple iPhone 4S was a surprise hit for Apple. No one had expected a device with such little cosmetic change to be one of the best selling iPhones to date. In fact, many analysts were betting on the device to be the worst performer of the iPhones released so far.

The reason why it had done so well comes down to a number of factors including timing, options available on the market, and a growing fan base.

The success of the iPhone 4S points to one thing which is that the iPhone 5 will be an even bigger seller than the iPhone 4S.

As with all new iPhone releases, the details about the iPhone 5 are shrouded in mystery and very few confirmed details are ever released.

One of the rumors that are very likely to eventuate include the fact that the iPhone 5 will have a quad-core CPU.

iPhone 4S plans in Australia have performed well for Apple and we have not yet seen cheap deals on them to date due to their popularity.
