Apple's unveiling of iOS 5 has got the technology world buzzing, as it signals that the iPhone 5 is one step closer to being released.
We've taken a look at some of the main features that will be incorporated into the operating system to see how they stack up against its chief rival, Android.
There were rumours floating around that RIM's BlackBerry Messenger (BBM) service would be incorporated into Apple and Android devices in the future. However, Apple emphatically squashed this at WWDC 2011.
Instead, the company unveiled iMessage, a service that will essentially offer all the functions of BBM to iOS users.
Apple will allow customers to send unlimited text messages using Wi-Fi or 3G. The iMessage service will also support the transfer of photos, videos, location and contacts. Apple is also touting the security of the service, which could be attractive to business users.
There are already third-party cross-platform messaging services available, such as WhatApps, but the launch of iMessage will make devices such as the iPhone more attractive to businesses.
Apple could have a service that is equal to and possibly better than BBM and Google Talk.
Apple will eliminate the need to connect future devices to desktop computers. Users will be able to set up an iPad, iPhone and iPod Touch wirelessly after purchase, and download updates over the air.
This will be welcome news to those who have struggled with iTunes, as it isn't always the most co-operative piece of software. Cutting it out will allow more freedom over device management.
This is a big step for Apple, but it's not exactly revolutionary. Android users have been able to set up their handset wirelessly and receive over-the-air updates pretty much since its inception. Even Windows Phone users have been able to set up devices without having to connect to a PC.
