The headliner in the tech world these days which is the brand new iPhone from Apple that is expected to arrive by next month has more good news than just the phone itself. The real big star that is behind all of it is actually its iOS7 along with essential upgrades that can also greatly benefit the owners of old Apple phone models.

The new Apple phone that is rumoured to be the 'iPhone 5S' is thought of to have a much faster processor and improved camera. The good news of it all is that its brand new iOS 7 software will also be installed on the previous three iPhone models starting from the iPhone 4 of 2010 and the other iPad except for the original one.

So what exactly are the main reasons why it is the iOS 7 that should be highlighted with the coming of the new Apple phone? Here are the top reasons why:

1. The owners of older phone models of Apple will surely feel the edge to have a shot at a free upgrade due to the coming software improvements. This can be a real advantage but can also be a backfire for the Apple company. According to experts, there is a great chance for users to settle for older and cheaper models instead of getting the new iPhone 5S since they can just have installed the iOS 7.

2. The iOS 7 will offer a more interesting visual design with a home screen that will be filled with icons through the iPhone apps with brighter sets of colours and designs much simpler. Its old faux textures will surely be gone.

3. When it comes to music features, the brand new iTunes Radio service will come with a new and flatter app icon that will remind you of the old school boombox radio. Other online music services like Spotify and Pandora will continue to get benefits from the assumingly big pool of current customers.

4. Some of the features of the iOS 7 will be very subtle but promises to become helpful according to tech rumours spreading around online. It will feature a new control pane with a finger all dragged up from the screen's bottom. This allows better and faster access to controls that are often needed to be accessed like the Wifi and the Bluetooth.

The rest of its other features include background effects that will allow apps to get updates even when it is running on the phone. In short, the iOS 7 will have features that users won't even get to notice easily but once discovered will surely be pleased about it. And remember, not just for the new Apple phone users.
