Unfortunately, the built-in 64 MB of memory is not enough and you need to dokupienie SD card. When the camera quality photos will unfortunately take a bit, so no high-speed Internet would be meaningless to send photos. Naszczęście we dodyspozycji UMTS technology, which gives us a quick trasmisje data. Sony Ericsson K800i also has a MP3 player and FM radio. Unfortunately the quality leaves much to be desired, and deviate from the standard camera. Please mention the PlayNow service, which quickly will have access to almost any song. This is a plus for people who do not have time to rip music at home. Send data to your computer easily via Bluetooth, infrared or USB. The phone has a big minus to a joystick, which is so all about. The problem has long been known, is an emergency and extremely surprised that the Sony Ericsson so stubbornly installs it in the future models of phones. Another disadvantage to large dimensions. While the height and width slightly deviate from the average, however, combined with the large thickness so that the phone presents itself as the "brick". To sum up the mobile phone Sony Ericsson K800i, you can easily combine a multimedia call, is all. The phone is certainly worthy of the lovers of photography, but not only. In my opinion, if only to sustain the joystick will have a lot of joy from it.
