Refurbished iPhone 4s

iPhone 4S
The design of the iPhone 4S is completely identical to the iPhone 4. It features the Retina Display 3.5-inch screen with a resolution of 960 x 640 pixels. The only aspect that was redesigned is the location of the antennas, to offer better call quality.
The iPhone 4Sis twice as fast as iPhone 4. Shoots still image dynamically; and when shooting Full HD video at 1080p, it does not lock. The new version of the operating system (iOS 5) makes the phone easy to use. Among the new features, the notification center stands out, which concentrates messages, tweets, calls, weather, and others in a curtain that is activated by simply sliding your finger down on the top of the screen. Another is iMessage, which sends encrypted messages between iOS devices and works on 3G and W-Fi, as well as integrating the Twitter account into the iPhone setting.
The keyboard of the 4S is QWERTY type and can be used vertically or horizontally. It has an extra button, which is used to activate the Siri function. The 3.5-inch multitouch screen has a resolution of 960 x 640 pixels, so the graphics are displayed in optimum quality. The iOS 5 has more than 200 new features, including the ability to sync content without using the USB cable and edit photos from your phone.
The computer's response is fast, thanks to the dual-core processor (A5), the same as the iPad 2.
Apple also improved the camera, now it is 8 megapixels to have a good resolution when taking pictures and video. It has autofocus (even when the screen is rotated), face detection, LED flash and the ability to record in Full HD (1080p) at 30 frames per second.Regarding its battery efficiency, the iPhone 4S delivers 8 hours of talk time in 3G, 14 hours in 2G (GSM) and 200 hours in standby time. When it comes to surfing the Internet, it offers 6 hours on 3G and 9 hours on Wi-Fi. And as far as multimedia is concerned, it provides 40 hours of audio and 10 hours of video playback. Apple called the iPhone 4S a world's phone, as it is a dual-band device, which means that it supports the two known bands, which are GSM and CDMA, which means that a iPhone 4S unlocked will be less necessary or more accessible in price. It also comes ready for HSDPA (3.5G), which has a speed of 14.4 Mbps and 5.8 Mbps upload (twice that of iPhone 4). The value of the iPhone 4S depends, as always, on its internal and physical characteristics. The refurbished 4S price will be a lot less expensive than a new one, a great option certified by Apple.
Regarding some of the multimedia features, AirPlay came in, a tool to stream video or audio (without downloading content. With Apple TV, for example, you can project your iPhone 4S screen into a larger one. Siri is also one of the most eye-catching features because since the 4S you can dictate her voice messages or ask for assistance. iCloud is another great tool that allows synchronizing documents, photos, videos, and music. The device has 1GB of RAM, which makes it fast even when you're doing more than one task. The iPhone 4S is available in 16GB, 32GB, and 64GB versions.
