Handphone TNT

Cell (short for cellular) phones, also known as mobile phones or wireless phones, are small hand-held phones with built-in antennas. Unlike home phones, cell phones can be carried from place to place with ease. This makes them a good choice for people who want to be in touch with other people even when they are away from the house.

Notable among these phones are the ones known as smart phones. Though earlier varieties of cell phones were developed without a microprocessor, most recent mobiles have been based on a microprocessor and a dedicated Operating System such as Android. These are also known as smart phones because they accommodate complex functionalities such as writing office documents, VOIP phone calls, etc.

A cell phone operates in conjunction with a cell tower that receives signals from a cell phone and forwards the same towards destination. Three widely used technologies in cellular phones are

a. GSM (Global System For Mobile Communication)
b. CDMA (Code Division Multiple Access)
c. iDEN (Integrated Digital Enhanced Network)

The protocols followed include 2G, 3g, 3.5G, and 4G (Developmental). Progressively, these technologies offer value added services like VOIP, broadband Internet, and video calls.

Camera in mobile phones

Namun antara smartphone BlackBerry Bold 9000 dan BlackBerry Curve 8900, mempunyai perbedaan yang signifikan pada hal – hal berikut ini :

Jaringan 3G
Bagi Anda yang lebih memprioritaskan kecepatan internet yang tinggi, sebaiknya Anda memilih BlackBerry Bold 9000, karena telepon pintar ini sudah didukung oleh jaringan HSDPA 850 / 1900 / 2100. Sedangkan BlackBerry Curve 8900 bukan 3G phone, sehingga menjadikan BlackBerry Curve 8900 kurang diminati dibandingkan dengan BlackBerry Bold 9000.

BlackBerry Bold 9000 mempunyai ukuran 114 x 66 x 14 mm dan berat 133 gram, serta resolusi layar 480 x 320 pixel.

You are probably contemplating on replacing your old and worn out mobile unit for a better model and many would agree that is an excellent idea. Smartphones and communicators nowadays are the trend in organizing your schedule, communicating, entertainment, and even keeping files handy. However, it is highly probable that you will get a minimal amount of cash in exchange of your old mobile unit and that would not be enough to cover the pricey tags of current Smartphone models. But you need not despair or just hold on to your dilapidated hand phone. You can get used Smartphones instead. Newer models of Smartphones come at least every six months and this means that more people are selling the older models at a bargain in used Smartphone websites. You are bound to get a great deal if you buy a used Smartphone instead of purchasing brand new. The features of a Smartphone are many and would really be to your advantage. Used Smartphones may not be the latest models out in the market but the high technology functions are already installed. Small and light weight, Smartphones can easily be carried around and you will have convenience right at your fingertips. Most used Smartphones on sale would include various accessories with them like vehicle charger adapters, GPS navigator, and maybe even a mini-USB. These are on top of the traditional wall chargers, head phones and ear plugs, maybe even a blue tooth enabled head set. You will find that buying a used Smartphone is the better idea if you would like to upgrade to a newer model of hand phone. Mobile units are infamous for their fast depreciation, thus it is more practical for you to buy second hand. You can also trade in your used Smartphone for a newer model as soon as you get tired of it or you find another Smartphone that you like better. Newer models boast of larger screens, double data base, and a larger memory capacity. The only disadvantage would be there are so many accessories you could put in you’ll probably end up carrying a different sack just for your mobile frills! When buying anything online, be it a used Smartphone or any other mobile units, you can really get the best deals. Nonetheless, make sure that you are getting your money’s worth still, by being an intelligent buyer. Do your research and always put your own safety and your financial safety in mind.

Hanya BlackBerry Bold 9700 sedikit lebih ramping dan ringan serta keypad QWERTY yang penuh.

Detail lain yang cukup manis : penutup baterai dihiasi dengan logo BlackBerry yang berwarna perak, ditutupi dengan kulit imitasi.

Kartu MicroSD untuk menambah kapasitas memori eksternal tepat terletak di antara penutup baterai dan baterai. BlackBerry Bold 9700 dan BlackBerry Bold 9000 sama sama menggunakan baterai lithium ion 1500 mAh.

Di sisi kanan layar, kita menemukan tombol untuk mengontrol volume suara, dan tombol kedua yang berfungsi sebagai jalan pintas default untuk kamera 3,2 mega piksel yang meliputi flash dan autofocus. Port untuk USB dan jack headset 3,5 mm juga terletak di sisi kanan layar. Di sisi kiri layar, tombol lain yang diprogram juga, mengarah ke browser. Layar berwarna resolusi tinggi 480 x 360 piksel.

Dibandingkan dengan BlackBerry Bold versi pertama, navigasi BlackBerry Bold 9700 menggunakan trackpad optik, sama seperti navigasi pada BlackBerry Curve 8520 Gemini. Dengan trackpad optik memungkinkan navigasi lebih cepat dan halus untuk memilih menu. Antarmuka tetap sama seperti pada versi sebelumnya : ikon yang dipilih akan ditampilkan dengan “fokus”, artinya, dengan sebuah sorotan berwarna biru.

Salah satu kelemahan utama adalah pada kamera yang hanya memiliki resolusi 3,2 mega piksel. Tetapi dengan touchpad, BlackBerry Bold 9700 lebih menyenangkan untuk digunakan, dengan navigasi halus dan tanpa suara di smartphone Anda.
