It's one of the cheapest handsets on the market to feature a full keyboard. On the features front, the phone features a horizontal sliding QWERTY keyboard with smartly placed numbers that looks like to be the top row of the keyboard when open, 2.1-inches screen (176?20), 2MP camera, FM Radio, Bluetooth, 40MB internal memory with microSD slot for memory expansion, music player and e-mail. Its designed for text messaging and one-click access to social media sites, like Facebook, MySpace, Photobucket, etc.
You've got the option of using the unusually-laid-out numpad too, if QWERTY isn't your style. With a built in music player, you can carry your tunes with you, in your pocket, and listen to them when you want. Additionally, Samsung B3310 features 40MB of internal memory plus a memory card slot so you can store loads of music.
