Current Iphone users are anticipating the release of the IOS 4 software update to unlock hundreds of new features on their existing Iphones.
It’s pretty cool that Apple can update things like the amount of zoom that the camera has and the ability to link a wireless keyboard with a software update.
The ability to gift apps also gives Apple a chance to add an additional revenue stream.
Multitasking which is only supported by the 3gs and 4 is also another cool feature.
More information on the features can be found here on apple’s website.
