The release of the first generation iPhone in 2007 changed the rules for smart phones, debuting innovative multi-touch user interface, slim design, advanced web browser and rich applications. Next came the iPhone 3G, with new features including GPS, 3G data and more color options. The iPhone 3GS introduced a faster processor and navigation with compass, more advanced connectivity, headphone remote support and a higher resolution 3 megapixel camera which also supports video and autofocus. The iPhone 4 was introduced in June of 2010 and featured a new case design, 5MP camera with 720p HD video and a front-facing camera for video conferencing. It was the first iPhone to be available on Verizon's network.
The latest model is the new iPhone 4S, introduced in October 2011. It offers the best battery life of any iPhone and is also the fastest iPhone yet thanks to a dual core A5 processor and faster graphics. The camera on the iPhone 4S has been improved with 8 MP still photos and 1080p HD video in addition to faster shooting speeds and lower light functionality. It continues to feature the LED flash and a front-facing camera for Facetime video chat. Download speed has increased from the previous iPhone 4 with a maximum speed of 14.4 MBps HSDPA - twice as fast as the iPhone 4. The iPhone 4S is a "world phone" which means that it can operate on any carrier's GSM or CDMA network if offered by that carrier, roaming internationally or unlocked. In the US, it is available on AT&T, Sprint and Verizon networks. Of course, there are also a wide variety of iPhone accessories available for any model.
The iPhone 4 and 4S both feature Apple's high-resolution retina display, with 960x640 resolution and an incredible 326 pixels per inch and 800:1 contrast ratio.
The iPhone 4S is the most world-compatible iPhone yet, supporting data with UMTS/HSDPA/HSUPA (850, 900, 1900, 2100 MHz) and CDMA EVDO Rev. A (800, 1900 MHz). It supports voice with CDMA and GSM/EDGE (850, 900, 1800, 1900 MHz). Every AT&T or GSM iPhone prior to the iPhone 4S has quad-band GSM that supports GPRS and EDGE data in addition to voice and SMS text messages. The iPhone 3G, 3GS and 4 on AT&T or other GSM networks support 3G data. The AT&T iPhone 4 provides faster uploads and quad-band data to make it more compatible with mobile data networks around the world. In February of 2011 Apple introduced the Version iPhone 4 a dual-band model that was compatible on the Verizon network in the United States. While often locked to a specific mobile network, often an unlocked iPhone can be found on eBay.
For people looking for ways around high iPhone prices, a refurbished iPhone could provide a savings. Also, a used iPhone, sold by individuals or from an eBay store, could be a cheaper choice. As with all eBay sales, please read all product descriptions before placing a bid. Be advised that used iPhones or refurbished iPhones may not carry a warranty or other standard features.
iPhone accessories such as iPhone cases and chargers can seem endless in selection. Even something as simple as an iPhone charger or iPhone case can be found in new, refurbished and used condition in various colors and styles. eBay offers a collection of all iPhone accessory products suited for any model. Browse the various iPhone accessories or one of our eBay sellers to search for a product that fits.
The selection only begins with new, refurbished, and used iPhones. The consideration on eBay includes condition, jailbroken, and unlocked iPhones, which collectively make eBay a perfect marketplace for shopping. Whether you're after a refurbished bargain 3G or a like-new jailbroken iPhone 4, eBay is the best place to start for iPhones and accessories. When planning to buy an iPhone, it is important to consider what power adapter, documentation and accessories are included from the seller. Please review the seller details before placing a bid. A jailbroken iPhone is one that has been modified by users to install unofficial and unsupported apps. GSM iPhones are often SIM locked to a mobile carrier. Some iPhones are manufacturer unlocked while others are unlocked by the seller through software modification or entry of a code. Every unlocked or jailbroken iPhone is not the same so it is important for shoppers to understand the exact nature of the purchase.
Every iPhone has the following features:
- Multi-touch screen
- Access to hundreds of thousands of apps
- Headphone jack
- Bluetooth connectivity
- 3.5" diagonal screen
