It has been 15 months since Apple began selling the iPhone 4 last June. The first iPhone was revealed in 2007, and the phone’s signature slick looks, high-resolution screen and intuitive software made it incredibly popular from the start.
A new iPhone is expected to have a number of changes, let’s have a look on some of the changes that will make it better from the first one.
-The biggest one is the inclusion of Apple’s latest iOS mobile software, iOS 5, which has been slated for release this fall.IOS 5 will include things such as wireless device setup and content syncing, and beefed-up camera, e-mail and Web-browsing apps.
-A new service called iMessage will allow iOS 5 users to send text messages to each other over Wi-Fi or wireless carriers’ data networks, while a folder called Newsstand will corral newspaper and magazine app subscriptions in one place to make it easier to find them.
-When it comes out, the software also will be available for Apple’s iPad, iPhone 4 and 3GS, and the two most recent generations of the iPod Touch.
-A new iPhone also is expected to include Apple’s forthcoming iCloud service, which will store content such as music, documents, apps and photos on Apple’s servers and let you access them wirelessly on numerous devices. The iPho
ne5 will automatically sync with the iCloud which will allow users to store photos, apps, calendars and documents without having them to store in the phone’s memory. Apple is also looking to tie up with top music label companies to license songs for the iCloud service.
-As for hardware, a new iPhone isn’t expected to look that much different from the iPhone 4, though it could be thinner and have a bigger screen. The existing iPhone is 0.37 inches thick and has a display measuring 3.5 inches at the diagonal.
-The iPhone 5 will have a rear-facing 
. Along with that, the iPhone 5 is expected to have a front-facing camera for video chatting.According to sources, Apple has filed several patent applications relating to 3D picture capturing to the US Patent and Trademark Office later in March. This indicates that the iPhone 5 might feature a 3D camera.
-One of the most notable hardware changes many industry watchers are predicting is the inclusion of a more powerful chip: Apple’s dual-core A5 processor, which is the same chip it uses in its current iPad. The iPhone 4 runs on Apple’s older A4 chip, and the move to a more capable chip should improve multitasking, opening apps and gaming.
-Analysts also believe Apple could also use the event to trot out new iPods and updates to iTunes music software.
