For me iPhone is the best type of phones , very easy - simple - no risks - no crashes if you know how to save it - no viruses - and expensive .
I advice you to Buy iPhone ( :
If you buy your iPhone from an Apple store, then you can get it unlocked without a sim card or you can get it with a sim card. The sim card is to do with the phone company/carrier that you choose, so if you don't mind your phone being locked to one particular carrier, then you can purchase the phone from that carrier at a reduced price with a contract, but the phone will be locked to that carrier.
I really like my iPhone. it's the best phone you could have , organized - fast - expensive - no risks - no crashes if you know how to make it safe - no viruses .
No iPhone comes with an SD card and if you had looked at the iPhone, you would see that it comes with a choice of storage options from 16GB, to 32GB to 64GB.
All iPhones need to by synced with iTunes so the way that you transfer photos etc., is via iTunes, so you need to transfer the photos from the SD card to your computer and then transfer these photos into iPhoto, so that they can then be shared by your iTunes library.
The iPhone® name has been used for a number of products, but is best known as the smartphone line released in 2007 by Cupertino, California-based Apple Inc. Apple’s phone popularized the use of touchscreens as a primary interface for a mobile phone. Beyond the aspects standard in most smartphones such as Internet connectivity and messaging, the features of the iPhone® can be divided into three main groups: hardware, media, and applications.
The hardware on the iPhone® has been one of its biggest draws. Based around touchscreen technology, it does not have a keypad; instead, a virtual keyboard and keypad are displayed on the touchscreen when required. The removal of the physical keypad lets the screen be much larger than that of similar-sized mobile phones. An accelerometer allows the iPhone® to react and change its screen display depending on if it is being viewed horizontally or vertically. The phone also has an internal flash drive to store data. Other hardware features include a digital camera, ambient light sensor, proximity sensor, speaker, Wi-Fi™ connectivity, Bluetooth®, and, in later models, A-GPS.
Besides just being a mobile phone, the iPhone® is also a fully-functioning media player. Songs can be transferred to its internal memory from most home computers as well as the iTunes® store, allowing entire music collections to be portable. Photographs and documents can be viewed on the device’s large color screen, as can full-motion video.
Applications are technically how the iPhone® works as a media player and web browser; the term, however, is also a general one that describes the downloadable programs the phone can run. The applications are extremely varied. There are applications which allow it to act like an ocarina, show the phone’s location on a map via A-GPS, randomly choose local restaurants for the user, play games, or just display interesting images. Applications are developed both by Apple Inc. and third-parties.
The iPhone® is usually sold “locked," that is, only able to use the cellular phone service of a specified provider. Some countries do not allow locked cell phones to be sold, so unlocked versions are available legally in those areas. In addition, hackers have been able to unlock the iPhone® with limited success for use on unauthorized networks.
Apple Inc. was not the first company to release a product called an iPhone®. In 1998, InfoGear Technology Corporation sold an Internet appliance that combined telephone and Internet capabilities. Cisco also released a voice over Internet protocol (VoIP) with this name through its Linksys division in 2006.
An app store is an online store where people can purchase applications for mobile devices. The original app store was the App Store run by Apple to provide applications for its iPhone® and iPod Touch® users, and other companies picked up the concept so that they could create and sell applications to their users as well. Applications in an app store can vary in cost, from free downloads to quite costly ones, depending on who developed the application and its purpose. Most paid downloads are relatively low priced.
Many manufacturers design apps themselves as they respond to user feedback from members of the public using their devices. The app store can also include apps from other developers, with the manufacturer reviewing the applications to confirm that they are functional, safe, and work as intended. Staffers may also rate applications to address concerns about young children accessing mature content, and to help people who are concerned about offensive content avoid apps which may upset them.
Apps are designed to expand the functionality of a mobile device. They can include things like personal planners, games, joke programs, and a wide variety of other types of applications. In order to be included in an app store run by a manufacturer, applications must generally be coded so that they conform with a very specific standard; many manufacturers release their standards and specs so that programmers can design apps for their devices. App stores which are run privately may not have such strict standards.
Users can typically access an app store from their mobile device, with some manufacturers providing a hot key which users can use to go straight to the store. Once there, users can search for an application by name, or browse by type. Often, many competing applications serve more or less the same function, with users choosing by price, design, reputation, or style.
When people download at an app store, they may be prompted for a username and password which is linked to financial information stored by the store itself, or they may be asked for a credit card number. People should be careful about downloading, confirming that their information is stored securely and used responsibly and that they are downloading the applications they intend to download. They should also be aware that the offerings in a third party store may not be vetted for safety, which means that they could potentially download something harmful, such as an application with an embedded virus or an application which collects personal information.
Creating iPhone® web apps is a technical task which requires advanced computer skills. This explanation will assume you have these skills and will instead give an overview of the process of developing an iPhone® web app and getting it into the app store.
The first rule of successful iPhone® web apps is to create something which solves a problem. You should create an app because there is a need for it, not simply because you've found a way to do it. As a guideline, look for a subject area where there are already several apps available, showing there is a good general market for the subject, but where no existing app meets the specific needs of the one you are planning.
To develop iPhone® web apps, you'll need to join the official Apple developer program. This costs $99 US Dollars (USD) in most cases. There is a $299 USD Enterprise program, but this is only needed if you want to distribute apps across a corporate intranet. Commercial apps aimed at the public can be covered by the $99 USD program.
It's also wise to download the iPhone® software developer toolkit. This includes a variety of tools for making sure your app is fully compatible with the iPhone® and iPod touch®. It includes an emulator so that you can see exactly how your app will look and work on a real device.
The process of creating the app involves three main stages: design, programming and testing. All are vital and it is worth planning as much of your work in advance to avoid unnecessary hiccups. At all stages, you should pay close attention to your intended market and the needs of customers. Independent testing by users from your target audience is particularly important as this will pick up problems you will not spot yourself.
Once created, iPhone® web apps must be submitted to Apple for approval. This is a two-part process. The app will be tested to make sure it will work on the iPhone® and iPod touch® and will not pose any security risks. The app will also be vetted to make sure it does not contain unsuitable content. There is some leeway for apps which will be marked as adult only. Some content will always be rejected, while other approval decisions by Apple may appear inconsistent, so it is worth checking in advance if you expect to encounter any problems.
