they can do the things faster on their phone.

Apple didnt specify about the RAM used in iphone 4 but according to Engadgetblog, it is

512 MB. If this is true that means then its a big advantage over the iphone 3gs and it makes

the phone unbelievable faster.

The display of this phone is Retina display. This means if you want to try to find a single pixel

on the phone screen then you will not be able to do that. The text and the pictures are really

clear and sharp and it looks like best device to play games on it. This is one of the major

selling points of this phone.

will pick the iphone then you will automatically know that how to use the iphone. This is

because the user friendly software of Apple. In iphone 4 Apple introduced the new operating

one application on iphone and switch between them easily. Like this anybody can do more

than 1 task at the same time without stopping previous tasks. This function is only available

in iOS 4.

The additional features which are included in iOS 4 are lots of. This is the platform of theworlds largest collection of mobile applications with over 200,000 apps. This is highly

efficient from the moment you turn on your phone and all application run in a safe

environment and one application cant use the data of any another application. iOS4 helps to

protect the sensitive data because it uses the encrypted network communication. It also

helps in protecting the data in the phone. You can setup a password for your phone to stop

the unauthorised access and you can set the password attempt so that data can be deleted

after particular unsuccessful attempt to open the phone. iOS4 is designed to operate the

phone in 30 languages and it is easy to switch between them and the voice control system

So if we look on the usability of iphone, we will find some main point which makes it a goodsmartphone to use:

2.1.5 Usability Issue in iphone:

The main issue that iphone 4 is facing now is the problem of call drop and this is because it

use to lose the signal while you are talking on the phone and this was the problem basically

every iphone 4 user is facing. Apple gave the statement about this problem is that you are

holding the phone wrong because the outer steel band works as an antenna for iphone 4

and if you will hold phone from its outer antenna then it will lose the signal. Apple suggestedto use iphone covers to resolve this problem.

It is hard to type in iphone because of its touch keypad where we need to just use one finger

at time and while typing its a common mistake to type a wrong word because you need to

take care all the time that you are pressing a right key. Its not something like a keyboard

where you can feel keys with your finger and can make sure that yes you are typing. If you

are typing something wrong on iphone then to correct it you need to tap on that word on the

exact location or you need to delete the whole word and need to write it again. This makes it

annoying sometime.

One of the main problems with iphone is, its Bluetooth. It is not possible to send files from aniphone to any other phone via Bluetooth. You can just send the files from iphone to iphone. It

makes this feature limited to iphone. The same problem is in its new software Facetime

which is coming on iphone 4, in this feature you cannot video chat with non iphone user and

you should have Wi-Fi to use this feature.

The web browser of iphone doesnt really give full experience of web browsing because it

does not support Flash player and Java.

Like other smartphones, iphone also have one main problem that its battery life is so poor

and if you are addicted to this phone and you use this phone so much then its better to carry

one extra battery with you and this is something a user really want to see the improvement inhis iphone.

These are some main issue which needs the attention of iphone engineers so that apple can

provide a better smartphone experience to iphone users.

Background of BlackBerry and Its Smartphones

BlackBerry is a very common name of the market of smartphones and it is known as one ofthe best smartphone company. BlackBerry only makes smartphones so its focus is always

on smartphones and it is the biggest competitor of Apples iPhone.

History of BlackBerry

BlackBerry was developed in 1996 by a Canadian company RESEARCH IN MOTION (RIM).

RIM was founded in 1984. The first BlackBerry was a two way pager which was able to send

and receive email and text messages but it was not able to use as a mobile phone. The

BlackBerry smartphone was originally released in 2002 and this series was BlackBerry

857/957, which was able to make phone call as a mobile telephone and it supports push

email, sending and receiving text messages, internet browsing, as a fax and other wirelessservices and many other PDA services like phone book, calendar and so on. This was a

great example of a convergent device. The BlackBerry got hit in early years because of its

ability of emails.

Mainly in all models of BlackBerry (except Strom) have a QUERTY keyboard so that it

makes easy to type just with thumbs and in the middle it contains a scroll ball or a touch pad

in new models which helps in system navigation and it works as a mouse.

From the beginning, BlackBerry is known as a Business phone because it uses the best

technology and it comes with many great features which helps a business person in many

ways. This phone is best of both entertainment and business requirement.

The next series of BlackBerry was 5000 and 6000. In late 2003 as the demand of CDMA

phones was increasing, BlackBerry released it new model BlackBerry 6750 which was a

CDMA enabled phone.

RIM continued to release CDMA versions in the coming 7200 and 7250 series models ans

the additional feature which were added in these models were the Bluetooth capability in the

phone.

As the size of the phones was going smaller, people started feeling BlackBerry a bulky

phone because of its QWERTY keyboard. In 2006 BlackBerry introduced its new seriesphone PEARL with the ability of sure type keyboard. In this, there were two letter in one key

to make the typing speed fast. This helped to reduce the size of the phone. Pearl originally

released for GSM network but in 2007 it was also released for CDMA networks.

After that the new series was BlackBerry 8000 series which increased the competition of

smartphones. The 8700, 8800, 8830, and 8820 models were released under this series and

the only thing which was missing was camera in the phone. These all phones were basically

developed for professional to use in places like courtroom. But when the Curve series

released the camera and Wi-Fi was included in device.

BlackBerry release the Bold series in 2008 and the latest Bold series device is BlackBerryBold 9700. BlackBerry also released its new phone Torch 9800 in USA but it is not released

Functionality and Usability of BlackBerry Torch 9800

This phone is straight the challenge to apples iphone 4 and it gives a hard competition to

iphone 4 or we can say BlackBerry is introducing this phone to give a hard competition to

iphone 4.

Lets have a look on the hardware and software specification of this phone and their

usability.

Hardware in Torch 9800

The Torch is a classic product of the blackberry because it has both the 3.2 inches touch

screen which comes with sure press feature and a full keyboard which seems like the

mixture of blackberry bold and blackberry storm. This feature makes it excellent for both

users, first who like touch screen and the second who likes a QUERTY keypad. It supports

the feature of multi touch so that you can also zoom in and zoom out with the two fingers on


11/14

the screen. It has the led light on the top like bold for notification of new call or message and

for any other notification,

Torch comes with 5MP camera with flash, which gives the features of image stabilization,

auto face detection and with new and different photo modes, which is again an advantage

on previous models but the video recording is in VGA format in this phone which also give agood clarity of videos. This is again will be loved by those user who wants to click some nice

pictures from their phone so when they go somewhere they dont need to carry an extra

camera with them.

This phone has the optical track pad as previous version of BlackBerry which is on the front

of the phone and very easy to use and with just touching a thumb on the track pad you can

easily control the whole screen of the phone with a cursor and click where ever you want by

clicking the track pad, so unlike iphone you dont need to move your finger on the screen of

the phone. This phone is integrated with 512 MB flash memory/ 512 MB SDRAM, and 4 GB

eMMC (inbuilt device memory) + 4 GB media card included, so the total memory is 8 GB but

this memory is expandable up to 32 GB which seems like more than enough for a mobile

phone. So you can expand memory as per your need and unlike iphone you dont need to

buy a phone with lots of memory by paying extra.

The battery life of this phone is good. The standby time on GSM is up to 18 days and up to

14 days on UTMS. GSM talk time is 5.5 hrs and UTMS talk time is 5.8 hrs, music playback is

up to 30 hrs and video playback is up to 6 hrs.

Torch 9800 is integrated with brand new operating system which is BlackBerry OS 6 and

according to BlackBerry this is the fast operating system which gives a freedom to explorethe phone in a new and fast way. The size of this software is 122MB.Blackberry came with

two views in this phone; a window that shows the application at the bottom and it can be

slides up and can be hided. Not only it can be bring this window up onto the home screen

and scroll vertically on it, but it can also be swipe side to side for creating the different

groups of applications, like "favourites" or "media", which helps in quickly access of your

favourite applications without entering in main menu screen which saves time and effort of

the user. It also consist a persistent notification on the main screen a small row of icons

which is on the top of the page. It makes easy to know about the feeds of social networking,

email, SMS, call, and calendar alerts all in one place.

Torch has a new webbrowser is the biggest addition in OS 6 which is faster than previous

version and it gives the features of pinching and zooming and with this browser you can also

open more than one web page and can swap between them which was not available in the

previous version of BlackBerry. No doubt this is one of the best web browsers in the market

and it is really very useful for those users who basically use their phone for internet. This

web browser also supports java and HTML so it becomes easy to open any website which

supports any of this language.

Torch comes with engaging multimedia features with the space of 8GB of memory which

gives a large room to media files and gives a brand new experience of media but if you need

more space then you can also expand memory according to your usages.


12/14

With the help of new social feed feature, it is easy to access all your social networking

account from one place and operating them without swapping between different pages

instead of this it has a drop down menu from where u can directly select that which

networking site u want to open quickly and this will be loved so much by those people who

like to use more than one social networking sites on their phone to keep in touch with their

friends and relatives.

The one big achievement of blackberry is its messenger which is basically available in all

phones of blackberry and which makes this phone different from another phones.

the phone and you can add somebody who has blackberry via that unique pin number. Its

Usability issue in Blackberry

Blackberry is a tremendous smartphone but its also not the perfect smartphone. There are

some issue users are facing in their blackberry.

The main problem in blackberry is that its screen frozen. Sometime it happens and you

cannot access the phone then you need to take out the battery out of the phone to reboot it

again and it takes another 5 minutes to reboot the device. Other problem blackberry users

are facing to access their emails from their phones but it can be because of network

problem.

Users are also not so much comfortable with the keypad of blackberry because the keys are

so small and they dont have enough gaps in between the keys which makes it hard to type

the correct character. In the early review of blackberry torch, people find that the touch

screen is not so good as in the iphone which doesnt satisfy those user who love to use

touch screen compare to a keypad and the other thing is there is no option on the screen of

the phone to pick a call so you need to press the receive call button to pick the call and it

was something that blackberry engineers forget to add in a touch screen phone.

Users are also not satisfied with blackberry application world because when we compare

blackberry application with apple apps then we will find a big difference that iphoneapplications are much useful then blackberry. This is the main area where blackberry needs

to think if they want to beat iphone.

Like other smartphones, blackberry also facing the problem of poor battery life and users

really want a good battery for their smartphones and expect that blackberry will come with

the solution.
