iPhone OS 4.0 revealed!

iPhone SDK 4.0Today, Apple have announced the intentions of version 4.0 of the iPhone OS, one year after the revelation of the groundbreaking iPhone OS 3.0.

The software itself will ship in the Summer and the developer preview SDK will be available download today through the iPhone Developer Portal.

Many iPhone enthusiasts have long been discussing the idea of multi-tasking support for the iPhone… but Apple have finally done it!  Apple are even claiming that their implementation of multi-tasking is the best yet, amongst other smart phones, although it is only available on iPhone models 3GS or above (i.e. not the 3G model) The process of switching between applications is made possible by double-pressing the “home” button (the big round one at the bottom of the iPhone) to reveal a “mini dock” of open applications.  Apple claim that multi-tasking will not affect performance of battery life, but this is yet to be seen.
