Contrary to what the general opinion suggests, the upgrades are significant. While the dual core processor may not give the illusion of the extra power when compared to the 4 in most usage scenarios, but the moment you open HD games, you know what you have spent the extra money for!

More power; Siri adds a fun element; iOS 5 brings in a lot of new features; Higher spec camera does very well

Looks exactly like the iPhone 4; Costs a lot of money

Apple never specified what the "S" stands for in iPhone 4S, and it may as well stand for Siri. Sure, the fifth-generation iPhone's superb camera and speedy dual-core processor are classy additions. But Siri is the reason people should buy this phone.

Siri is the best androgynous unpaid intern you'll ever meet; Dual-core guts make for faster apps and a smoother interface; Camera is much-improved; Call quality gets a boost

Siri is limited in what it can do and understand; Looks the same as the iPhone 4 - what's up with that? A two-year contract means you may not be eligible for the best upgrade pricing

Why buy any other phone? This phone has the features you could possibly ask for and then some. The fluidity of how everything in the phone moves makes it very pleasing to the eye, not to mention built in Retina Display.

-Fast; -Fluid; -Functional (able to do things other people can't; -Wide Range of the Best Available Apps/accessories; -Retina Display; -Simple one touch home screen physical button; -Siri; -Easy and pleasant; -8 Megapixel Camera; -iMessage; -iPod

- This NEEDS a case unless you plan on being extremely meticulous all the time with the original glass

ICONIC GADGET SELLER Apple's Iphone 4S looks just like its predecessor, but as we said in our initial hands on review , it's what's on the inside that counts. Works right out of the box One of the best features of the Iphone 4S, in our opinion, is that it works right out of the box.

A5 processor; 8MP camera; gaming experience; Icloud

Same design; Siri isn't yet fully capable in the UK; Nothing

Screen protectors come in a pack of three and are much better than the cheap alternatives available else where. They do not inhibit the use of the touch screen whatsoever and are reasonably easy to apply (just fiddily to position, expecially on the first try). Would highly recommend!

Worst mobile they are selling used mobiles I got a mobile with scratches backside of the mobile with no earphones and with duplicate charger

That said, if you're looking to upgrade your iPhone, or swapping from a different handset, the Apple iPhone 4S is a fantastic smartphone. Stylish, well made, easy to use and packed with features, there's loads to like.

The phone also has dictionary support implemented throughout the UI. This means you can select a word in any native app and choose to see its definition. Moreover, dictation support has also been integrated, and it does the typing for you - provided you speak slowly and clearly into the mic.

Fluid UI; Impressive camera; Spectacular display; Great audio quality; Superb battery; Excellent for gaming; Rich App Store

Ridiculously expensive; iTunes dependability; Limited codec support; Siri is not practical; No FM Radio; No file sharing over Bluetooth; No mass storage mode

No doubt the phone is still the best and can even compete iphone 5. I've used a lot of smart phones but never really liked to use apple phones. I thought they were boring and dull. I thought people just use it to show off. But never had the best smartphone experience. Everything so clean and fast.

Very snappy; Crisp display; Handy; Awesome camera; Zero percent lag

A bit smaller display; Heavy; Low battery life after updating to iOS 6.1.3
