Today, the use of a Wi-fi mobile phone or a 3G phone serves as a part of the options that individuals adopt for fast Internet connectivity. It is the utmost interest of people to have an access to the Internet since many human activities are associated with it. This guide will help you to appreciate the functionality of phones that can solve your problem of connectivity.
Of course, there are many phones that come with Wi-Fi and/or 3G connectivity, but iPhone has been noted to be a special product. Here, this gadget is being considered as a case study of what people can get from a Wi-Fi mobile phone and a 3G phone since most phones on the market have similar functionality.
You can have Internet connectivity when an iPhone gets connected to 2G wireless networks - an EDGE or GSM network or a local area Wi-Fi. With the advent of the iPhone 3G, there is support for UMTS and HSDPA 3.6. The iPhone 4S provides support for HSUPA network while the iPhone 3GS and iPhone 4 provide support for HSDPA 7.2.
When your gadget discovers a Wi-Fi network, it will ask to join it, prompting for a password if required; it can manually join a closed Wifi network as well. If you own the iPhone 3G and later models, you can deactivate the Wi-Fi, the Bluetooth, and the 3G capabilities when required.
The iPhone 3GS offers a maximum download speed of 7.2 Mbit/s. However, the size of apps, media files or email attachments you may want to download over a cellular network should not exceed 20MB. Use Wi-Fi to download larger files since the network has no file size limits; if there is no Wi-Fi network, open the files on Safari - that's the only workaround. Safari happens to be the web browser for the Apple gadget.
Moreover, you have access to an app that makes it possible to view videos on YouTube. The app streams the videos after having encoded them with the H.264 codec. In addition, you can look up updates on stock quotes and weather forecast with another available app that easily connects your device to the web.
Wherever you may be, you can access the net as often as you want if you own a Wifi mobile phone. Depending on the brand of phone you buy and the network carrier you adopt, you can enjoy both cellular and Internet connectivity with your mobile phone.
