iPhone 4S Review – is it worth to upgrade?

Do you even think about upgrade iphone 4 to iphone 4s due to new Siri technology or the upgrade was worth the 2 year, someone said, Siri for now is nothing special and the camera and video works just perfecly on iPhone 4. Although you don't notice a speed issue, how about your iphone brain?

It's much the same way Apple handled the 3G and 3GS upgrade, only this time for the iPhone 4S, thereare more changes. And they're all effectively invisible. We've been living with the iPhone 4S, iCloudand iOS 5 for a few days, judging by the numbers, familiarity can sometimes be a good thing,especially when you consider the excellent design of iPhone 4, something most companies have still yetto match.

However, as much has been improved since last year, iPhone 4S including new A5 dual-core processor,upgraded camera and the all new Siri voice assistant. There is a noticeable difference between iphpne4 and iphone 4s when loading applications and browsing the web, it isn't mind-blowingly faster. Forexample, unless you're restoring the data from an older iTunes backup, the 4S doesn't require acomputer for activation. An iCloud account can help you easily restore the phone, or set up as a new phone, but we can ask for iPhone /iPad/iPod to Computer Transfer to manage iPhone content and transfer files between iPhone and computer.

Apple gave a lot of attention to Siri and its capabilities, touting its convenience and ease using. While Siri is good fun of setting appointments, speech-to-text and checking weather easier. Whether or not Siri is a compelling enough reason to upgrade is up to personal preference, I think. I think what people most impressed with was the new upgraded camera in the iPhone 4S. The camera's had a major overhaul, now capable of taking eight-megapixel stills and recording 1080p video. It is a huge improvement than iPhone 4 camera was.

Battery life has also been improved. Apple claims 8 hours of 3G talk time, 9 hours of wifi use, 10 hours video playback and 40 hours of musical pleasure. In experience, we can say that when compared to the iPhone 4, all of these activities had less on battery.If you consider the iPhone 4S as iPhone 4 doesn't exist, then, yes, it's a powerful mobile device that offers a number of great services – iCloud, iTunes, Siri, new A5 dual-core processor, upgrade camera, the iPhone 4S is now the best phone from the Apple stable.

iPhone 4S is faster, but it doesn't do anything substantially different other than offering Siri. If you've upgraded, what are your thoughts? If you didn't upgrade, will you upgrade iphone 4 to 4S or get and unique iPhone case a ccessories to customize your iPhone?
