General Information

16GB iPhone 4S locked AT&T model. Will work on AT&T.

Now you can use your voice to use your iPhone. Just talk to Siri as you would to a person: "Do I need an umbrella?" or "Any great burgers around here?" or "Where's the closest ATM?" Siri not only understands what you say, it knows what you mean.1 It figures out the right apps to use to find the right answer. Then, just like a personal assistant, it answers you. Siri makes phone calls, sends messages, schedules meetings, sets reminders, and more. How much more? Just ask, and Siri tells you that, too.

Two cores in the A5 chip deliver up to two times more power and up to seven times faster graphics.2 And you'll feel the effects. Fast. iPhone 4S is quick and responsive, which makes all the difference when you're launching apps, browsing the web, gaming, and doing just about everything. And no matter what you're doing, you can keep on doing it. Because the A5 chip is so power-efficient, iPhone 4S has outstanding battery life.

This just might be the best camera ever on a phone. And with all-new optics, it just might be the only camera you need. Because behind every shot, you've got 8-megapixel resolution and a custom lens with a larger f/2.4 aperture. Not to mention an improved backside illumination sensor, excellent auto white balance, advanced color accuracy, face detection, and reduced motion blur. It all means that no matter how many people, how much light, and how much action you capture, everything looks exactly as it should. And just wait until you see the photos.

Shoot stunning 1080p HD video everywhere you go. With all-new optics, the light is always right, the color is always vivid, and everything will look even better than you remember. Video stabilization steadies shaky shots. And you can edit video right on iPhone and share your lush life as fast as you shoot.

Pros: You can play Flac and games to booth
Cons: Itunes is a pain at times
I recently upgraded my 16GB version to 64GB for less than 200 bucks.  I wanted to upgrade to the newer models, but I'm not going to waste my money on something that can play the same music for more money.
Anyways,  the sound from the Iphone 4s is excellent to my ears.  It's gets better with different audio apps in its stock form.  You don't need to hack it, to unlock it's full audio potential.  Just buy some apps and call it a day.
So my first app that I enjoyed for a while, was the Denon audio app.  You can make your own eq curves.  Sounds really good without an amp.  
Second app is BBE Pro.  This app will bring out the bass along with sound stage, when hooked up to an amp.  Love this app with my bass heavy mp3's.  
Third app is Kaisertone.  This app will give you a 30 band EQ and a few DSP's.  This is my favorite to play Flac files with.  
Once is a blue moon I'll use Neutron.
Now I listen to my music a few ways. 
1. Through the 30pin connector, into my FIIO E12A.
2. Through the audio out, into my FIIO E12A.
The first method you get what you get with FIIO L9 or L11 connector.  With the L11, you have to choice to use your own cables and charge/sync at the same time.  But I can't barely tell any SQ differences between cables.
The second method you get get to hear a difference in your cables you use.  Friends and myself can hear SQ differences when swapping cables.  I like this for when I want a mechanical EQ just to tweak my sound faster depending what I listen too.
+1 for the iPhone 4S.

I re-set the phone and now use it as a dedicated player for Tidal (over WiFi), amped by the excellent CEntrance M8.
Pros: Connectivity, Price Reduction, SQ, UI
Cons: "High Resolution" support
I use the 30pin line out dock on my iPhone 4s as a portable source. As a portable source the iPhone 4s makes an excellent choice for lots of reasons that I'm not going to explain in this review. Here are the highlights that do it for me. I'm going to make the case that the iPhone 4s make a great dedicated lower cost portable source. The best function the 4s has going for it is web connectivity. I want to listen to the 'Ex Machina' Soundtrack By Portishead’s Geoff Barrow And Ben Salisbury right now. I can do that with a smart phone! I want access to the millions of tunes in the Tidal music catalog I can do that to. I can load WAV files onto the 4s granted the iPhone won't do 192khz / 24bit or DSD... well la dee freaking da, I don't care. I can't consistently tell the difference between 16bit and 8bit tracks. Try going to, select the tab blind audio test and take the '16-bit v/s 8-bit Blind Listening Test' for yourself. has the sound quality measurements on 4/4s, I realize that the measurements and numbers are far beyond anything the human ear can quantify, I know my ears can't. 
I do think that using the line out dock is the way go. Bypassing the on-board amp circuit and using a dedicated external amp offers superior sound quality but you already know that. 
The iPhone 4s will soon be three generations out of style and the price will reflect this. I think this is a steal that offers a very high price to performance ratio.               
The big issue is if the 4s will run IOS 8.4 when it comes out? Other wise you will have a $460 phone that will not be able to get the Beats Apple streaming service which comes with 8.4.
My Apple 4 iPhone has been left behind on any new IOS updates also.
iPhones, iPads and iPods in general are very underrated here because of the lack of science behind Audio. Almost any person here thinks that an iPhone 4S for example sounds 'poor', and that they need an external DAC because the internal 'is so ****ty that anything external will sound better than it', which is a giant lie, subjectively and objectively, as shown by the measurements. Great review.
