Why? Here goes…

Laptops and computers have enough space to house powerful processors and large RAMs, to enable them to multi-task with ease. The smartphones, being smaller in size, have restrictions on the processor and the RAM that they incorporate within them. Even if a powerful processor and a capacious RAM are housed within, problems crop up with battery life. The multi-tasking might drain out battery very soon, which spoils the whole idea of owning a mobile phone.

However, smartphone multitasking is offered, but with a difference. In laptops, applications and programs can run in the background. Even if the user is looking at one particular app, there will be many other apps running behind the scenes. Thus, you can download a file, listen to music, let your email and social networks update themselves and more at the same time.

In smartphones, when a user switches from one application to another, the background app is paused. It will remain in the memory (RAM), but without doing anything. When the user switches back to the background app, it will resume from where it was left. Then again, if there are too many background apps open, then the operating systems are designed in such a way that, some apps are suspended. Usually, those apps that have not been visited for a long time are suspended. This means that, their current states are saved and they are terminated from the memory. This frees up space in the RAM for better functioning. When the user switches back to the app which has been suspended, its state is restored and the user will be able to resume from where he had left it.

This is basically how mobile phone multitasking works in most platforms. Windows Phone 7 multitasking is also based on this logic. Very few apps are allowed to run even in the background, when the user is working on something else in the foreground. Downloading of files, playing music using a native music player etc are some examples. However, there’s an extension to background apps in Android multitasking. Google allows true multitasking even with third party apps. Apps which need to run in the background should have something called as a service. This service will perform the same tasks as the app itself, but it will lack a user interface. It will thus run in the background. The app and the service work as a client-server model. Many apps use this model for their functioning and hence enable multitasking.

However, this kind of multi-tasking takes a toll on the battery life of the device as mentioned earlier. Therefore multi-tasking and battery life come as trade-offs.

TetherMe

This app has been created by BigBoss. It has been successfully tested on iOS versions from 3.0, all the way up to 4.0.1.

Presently, the TetherMe app only supports USB and Bluetooth tethering. You will be able to link your laptop or PC to your iPhone, via USB or Bluetooth only. You will not be able to convert your iPhone into a wireless router or a WiFi router, to enable other devices to access the internet in its hotspot. There are reports that a new version of the app, that supports such WiFi tethering will be released soon. However, nothing is confirmed yet.

This app is said to allow editing the carrier bundle too. This is where one enables tethering option, MMS option etc. for the phone. However, for the iPhone a signature check is done to restrict the user from accessing these settings. With TetherMe this signature check is said to be bypassed. Since, tethering with TetherMe is similar to enabling native tethering on the iPhone, it has been said that this app can be installed on non-jailbroken iPhones too.

After installation of TetherMe, no icon is created as you would otherwise expect. This app has to be accessed from Settings>General>Network; or using Tethering Toggle with SBSettings.

One of the best reasons to use this app is the cost. The TetherMe price is just $1.99 from the Cydia store. Other tethering apps that are available in the market are much more expensive. For example, take PdaNet, which costs $29 for a license or even the popular MyWi, which is priced at $20 or so. However, one aspect to be considered is that these other apps do offer USB as well as WiFi tethering.

Cheap and effective, TetherMe might soon take over as the most popular iPhone tethering app.

At the bottom of the 3.5 inch display screen lies icons for the phone menu like Safari web browser, the mail folder and ipod player. Features like Calender, camera and other settings sit to the top of the display. All the features listed are most essential helping users to perform what they wish with just a touch.

Fluid animation leads you between different function and you can zip between them quickly. A good deal has been made out of the iPhone touchscreen and truly so. Though this is not the first handset to come out with touchscreen, this is the first smartphone to come out gathering so much expectations and attention from the audience. Depending on what you want to perform with the iPhone, the touchscreen serves your purpose like a keyboard, number keypad, music and video player, safari browser and more.
