Samsung i780 is Smartphone with Windows Mobile Professional (touch screen) operating system. This smartphone also known as Blackjack II, this is the successor or Samsung SGH-i600 (the smartphone with Windows Mobile non touch screen). The interesting about Samsung i780, beside full qwerty keyboard and touch screen, the navigation can be easily by using touch navigation as joystick. So, we can move the cursor with our finger at the joystick location.
Samsung i780 have 256MB internal memory ROM which is divide into about 110MB for running program and 150MB for internal memory which can be use to install software. This smartphone also have external memory slot type microSD. Yes, we can install almost all programs at external memory, but there will be different speed when install at internal vs external memory. For messenging software such as email, it is recommended to install at internal memory, other wise sometime the external memory will be act strange and have to be restart or soft reset.
This is 3.5G smartphone, Samsung i780 can connect to GSM900, GSM1800, GSM1900, UMTS2100 with data type CSD, GPRS, EDGE, UMTS, HSDPA at maximum data speed 3,6Mbps, this is depend on the GSM provider. Samsung i780 have 2 cameras, one at front side for video call with VGA resolution, and the other camera at back side with maximum 2 megapixel. The back side camera also can record for video with unlimited memory size, the maximum resoultion is 320x .
Almost all new high end cellular phone also have GPS, this Samsung i780 also have internal GPS. Usually some provider will be package together with trial usage of map for free. But if you did not get the free trial map, we still can install other software such as Mapking or Garmin XT which can use for Windows Mobile. Bluetooth and WiFi already available at this smartphone. Like other Samsung smartphone, the data USB connection port also can be connect to recharge this smartphone, maybe almost all PDA also do the same way.
The Samsung i780 Display TFT with 320x320 pixel 2.5 inch touch screen. The size of display smaller then other standard PDA can make the 1000mAh battery lasting for more time. The data connection also can make battery longger life. If you only use this phone for sms, receiving email, browsing and chatting, better to choose only GSM for data transfer. Because if we use always GSM data connection, it can have more than 5 times stronger battery then if we always activate the 3G (WCDMA) data connection
Overall I really like having this smartphone. The price is not so expensive for all Samsung i780 features. Thank's for Windows Mobile operating system, which can make us easy to install freeware or shareware software by internet. The design of the phone also nice and elegant. If you already known how easy and fun using Windows Mobile operating system, then you will be have new fun experience using this smartphone.
