The Good Dual-core chip keeps it faster than rivals. Excellent rear camera for quality, speed. Siri makes voice commands natural, accessible. iOS 5 helps Apple catch and maybe pass rivals. iCloud syncing and backup. Long battery life. Still a great display. 64GB option. Good feel in the hand.

Siri only goes so far; no third-party apps, not enough voice feedback, Call quality just so-so, Might benefit from a larger screen, 3G stops at 14.4Mbps; no real 4G yet, Design still somewhat fragile, Video a bit prone to CMOS effects

The iPhone 4S is Apple's best yet, and keeps the Cupertino brand front and centre in the minds of the prospective smartphone user.

Apple's latest iPhone ups the ante once again, thanks to its dual-core processor, iOS 5 software, and 8MP camera with 1080p video

There's a term used to describe the allure of Apple products and it was coined in 1981 by an Apple software designer. Legend goes that the reality distortion field, or "RDF", was what Steve Jobs spun to convince one of anything via charisma, hyperbole and that glistening veneer known as really,...

Incredibly responsive interface and touch-screen; notifications bar for events and weather; excellent camera; still the slickest hardware design on any phone; high-quality apps at an easy to navigate app store

iCloud data sync costs after a miserly 5GB; most of its best features available as a software update to older iPhones

The iPhone 4, even well over a year after its debut, is a remarkable piece of hardware that has no trouble running the latest version of iOS. Sure, there's faster hardware out there but the smooth user experience in iOS even on the single core A4 processor is still top notch.

I was a bit disappointed by the iPhone 4s. I thought that it would be bigger advancement compared to the previous model. To me, the iPhone 4S is full of new features, but these features are absolutely useless. These features are simply pointless and not worth paying for.

According to me the best iPhone you can buy. It is solid, which means that it can handle a large number of bumps and knocks. It fits with iOS 6, but also works with iOS 7. It gets a little tougher then. iOS 8 and 9 the state of disrepair.

We review the Apple iPhone 4S, the dual core, Siri-toting version of its popular iPhone 4 handset

Still a looker; excellent build quality; impressive performance; camera and video quality greatly improved

Siri not so useful in the UK; iOS 5 can feel dated at times

It's been 15 months since Apple released the iPhone 4. This has left many iPhone, and would-be iPhone customers, anxious for what the company planned to bring next. As we learned recently, the iPhone 4S it is : same body, same screen, same construction, same look as the iPhone 4.

Excellent hardware construction; easy interface; iOS 5 + Siri; excellent camera; speed to spare

Smallish screen; no 4G; no user replaceable battery

I am not an Apple fan after having it for a while, so I will be trying HTC next time, had loads of good feedback about HTC's in my office. I felt slightly riped off by Apple & would prefer an Android now. I know many that are happy with this phone, but not me : (.
